Tyler Goodlet 609b91e848 Try out `@trio_util.async_generator` for streaming
Apparently it will likely fix our `trio`-cancel-scopes-corrupted crash
when we try to let our `._web_bs.NoBsWs` do reconnect logic around
the asyn-generator implemented data-feed streaming routines in `binance`
and `kraken`.  See the project docs for deatz; obvs we add the lib as
a dep.

Tyler Goodlet 3066b1541e Handle (shorter supported) minor-curve not-in-view
Solve this by always scaling the y-range for the major/target curve
*before* the final overlay scaling loop; this implicitly always solve
the case where the major series is the only one in view.

Tidy up debug print formatting and add some loop-end demarcation comment
lines.

Tyler Goodlet 32339cb41a Always show a minimum bars during startup
This is particularly more "good looking" when we boot with a pair that
doesn't have historical 1s OHLC and thus the fast chart is empty from
outset. In this case it's a lot nicer to be already zoomed to
a comfortable preset number of "datums in view" even when the history
isn't yet filled in.

Adjusts the chart display `Viz.default_view()` startup to explicitly
ensure this happens via the `do_min_bars=True` flag B)

Tyler Goodlet 12e196a6f7 Catch `KeyError` on bcast errors which pop the sub
Not sure how i missed this (and left in handling of `list.remove()` and
it ever worked for that?) after the `samplerd` impl in 5ec1a72 but, this
adjusts the remove-broken-subscriber loop to catch the correct
`set.remove()` exception type on a missing (likely already removed)
subscription entry.

Tyler Goodlet 5958acebe1 Add (commented) draft 1min OHLC time index logging
For the purposes of eventually trying to resolve last-step indexing
synchronization (an intermittent but still existing) issue(s) that can
happen due to races during history frame query and shm writing during
startup. In fact, here we drop all `hist_viz` info queries from the main
display loop for now anticipating that this code will either be removed
or improved later.

Tyler Goodlet 8d1c713a5a Always pass step to `slice_from_time()` in view mode
Again, as per the signature change, never expect implicit time step
calcs from overlay processing/machinery code. Also, extend the debug
printing (yet again) to include better details around
"rescale-due-to-minor-range-out-of-view" cases and a detailed msg for
the transform/scaling calculation (inputs/outputs), particularly for the
cases when one of the curves has a lesser support.

Tyler Goodlet 32926747c6 Always pass `step` to `slice_from_time()` in the `Viz`
As per the change to `slice_from_time()` this ensures this `Viz` always
passes its self-calculated time indexing step size to the time slicing
routine(s).

Further this contains a slight impl tweak to `.scalars_from_index()` to
slice the actual view range from `xref` to `Viz.ViewState.xrange[1]` and
then reading the corresponding `yref` from the first entry in that
array; this should be no slower in theory and makes way for further
caching of x-read-range to `ViewState` opportunities later.

Tyler Goodlet 712f1a47a0 Require `step: float` input to `slice_from_time()`
There's been way too many issues when trying to calculate this
dynamically from the input array, so just expect the caller to know what
it's doing and don't bother with ever hitting the error case of
calculating and incorrect value internally.

Tyler Goodlet 51f3733487 Handle "target-is-shorter-then-pinned" case
When the target pinning curve (by default, the dispersion major) is
shorter then the pinned curve, we need to make sure we find still find
the x-intersect for computing returns scalars! Use `Viz.i_from_t()` to
accomplish this as well and, augment that method with a `return_y: bool`
to allow the caller to also retrieve the equivalent y-value at the
requested input time `t: float` for convenience.

Also tweak a few more internals around the 'loglin_ref_to_curve'
method:
- only solve / adjust for the above case when the major's xref is
  detected as being "earlier" in time the current minor's.
- pop the major viz entry from the overlay table ahead of time to avoid
  a needless iteration and simplify the transform calc phase loop to
  avoid handling that needless cycle B)
- add much better "organized" debug printing with more clear headers
  around which "phase"/loop the message pertains and well as more
  explicit details in terms of x and y-range values on each cycle of
  each loop.

Tyler Goodlet fc98d66ffc Fix curve up-sampling on `'r'` hotkey
Previously when very zoomed out and using the `'r'` hotkey the
interaction handler loop wouldn't trigger a re-(up)sampling to get
a more detailed curve graphic and instead the previous downsampled
(under-detailed) graphic would show. Fix that by ensuring we yield back
to the Qt event loop and do at least a couple render cycles with paired
`.interact_graphics_cycle()` calls.

Further this flips the `.start/signal_ic()` methods to use the new
`.reset_graphics_caches()` ctr-mngr method.

Tyler Goodlet 7e6e04b7e2 Drop remaining usage of `ChartPlotWidget.default_view()`
Instead delegate directly to `Viz.default_view()` throughout charting
startup and interaction handlers.

Also add a `ChartPlotWidget.reset_graphics_caches()` context mngr which
resets all managed graphics object's cacheing modes on enter and
restores them on exit for simplified use in interaction handling code.

Tyler Goodlet f7dfe57090 Disable coordinate caching during interaction
This finally seems to mitigate all the "smearing" and "jitter" artifacts
when using Qt's "coordinate cache" graphics-mode:

- whenever we're in a mouse interaction (as per calls to
  `ChartView.start/signal_ic()`) we simply disable the caching mode (set
  `.NoCache` until the interaction is complete.
- only do this (for now) during a pan since it doesn't seem to be an
  issue when zooming?
- ensure disabling all `Viz.graphics` and `.ds_graphics` to be agnostic
  to any case where there's both a zoom and a pan simultaneously (not
  that it's easy to do manually XD) as well as solving the problem
  whenever an OHLC series is in traced-and-downsampled mode (during low
  zoom).

Impl deatz:
- rename `ChartView._ic` -> `._in_interact: trio.Event`
- add `.ChartView._interact_stack: ExitStack` which  we use to open.
  and close the `FlowGraphics.reset_cache()` mngrs from mouse handlers.
- drop all the commented per-subtype overrides for `.cache_mode: int`.
- write up much better doc strings for `FlattenedOHLC` and `StepCurve`
  including some very basic ASCII-art diagrams.
