Tyler Goodlet cc5390376c Use `Fsp` abstration layer through engine and UI
Instead of referencing the remote processing funcs by a `str` name start
embracing the new `@fsp`/`Fsp` API such that wrapped processing
functions are first class APIs.

Summary of the changeset:
- move and load the fsp built-in set in the new `.fsp._api` module
- handle processors ("fsps") which want to yield multiple keyed-values
  (interleaved in time) by expecting both history that is keyed and
  assigned to the appropriate struct-array field, *and* real-time
  `yield`ed value in tuples of the form `tuple[str, float]` such that
  any one (async) processing function can deliver multiple outputs from
  the same base calculation.
- drop `maybe_mk_fsp_shm()` from UI module
- expect and manage `Fsp` instances (`@fsp` decorated funcs) throughout
  the UI code, particularly the `FspAdmin` layer.

Tyler Goodlet fd31b843b9 Hide the unit vlm after the $vlm is up
Since more curves costs more processing and since the vlm and $vlm
curves are normally very close to the same (graphically) we hide the
unit volume curve once the dollar volume is up (after the fsp daemon-task is
spawned) and just expect the user to understand the diff in axes units.
Also, use the new `title=` api to `.overlay_plotitem()`.

Tyler Goodlet ce7c174059 Add `Axis.set_title()` for hipper labelling
Use our internal `Label` with much better dpi based sizing of text and
placement below the y-axis ticks area for more minimalism and less
clutter.

Play around with `lru_cache` on axis label bounding rects and for now
just hack sizing by subtracting half the text height (not sure why) from
the width to avoid over-extension / overlap with any adjacent axis.

Tyler Goodlet 80079105fc Add custom `.formatter` support to our `PriceAxis`
Allow passing in a formatter function for processing tick values on an
axis. This makes it easy to for example, `piker.calc.humanize()` dollar
volume on a subchart.

Factor `set_min_tick()` into the `PriceAxis` since it's not used on any
x-axis data thus far.

Tyler Goodlet 404f5d6d23 Factor (sub-)chart spawning into a admin method
Adds `FspAdmin.open_fsp_chart()` which allows adding a real time graphics
display of an fsp's output with different options for where (which chart
or make a new one) to place it.

Further,
- change some method naming, namely the other fsp engine task methods to
  `.open_chain()` and `.start_engine_task()`.
- make `run_fsp_ui()` a lone task function for now with the default
  config parsing and chart setup logic (and it still includes a buncha
  commented out stuff for doing graphics update which is now done in the
  main loop to avoid task switching overhead).
- move all vlm related fsp config entries into the `open_vlm_displays()`
  task for dedicated setup with the fsp admin api such as special
  auto-yrange handling and graph overlays.
- `start_fsp_displays()` is now just a small loop through config entries
  with synced startup status messages.

Tyler Goodlet 09fc901b0d Handle left axis case for x-axis label placement
For wtv cucked reason all the viewbox/scene coordinate calcs do **not**
include a left axis in the geo (likely because it's a hacked in widget
+ layout thing managed by `PlotItem`). Detect if there's a left axis and
if so use it in the label placement scene coords calc. ToDo: probably
make this a non-move calc and only recompute any time the axis changes.

Other:
- rate limit mouse events down to the 60 (ish) Hz for now
- change one last lingering `'ohlc'` array lookup
- fix `.mouseMoved()` "event" type annot

Tyler Goodlet 06fe2bd1be Support "volume" and "dollar volume" on same chart
This is a huge commit which moves a bunch of code around in order to
simplify some of our UI modules as well as support our first official
mult-axis chart: overlaid volume and "dollar volume". A good deal of
this change set is to make startup fast such that volume data which is
often shipped alongside OHLC history is loaded and shown asap and FSPs
are loaded in an actor cluster with their graphics overlayed
concurrently as each responsible worker generates plottable output.

For everything to work this commit requires use of a draft `pyqtgraph`
PR: https://github.com/pyqtgraph/pyqtgraph/pull/2162

Change summary:
- move remaining FSP actor cluster helpers into `.ui._fsp` mod as well
  as fsp specific UI managers (`maybe_open_vlm_display()`,
  `start_fsp_displays()`).
- add an `FspAdmin` API for starting fsp chains on the cluster
  concurrently allowing for future work toward reload/unloading.
- bring FSP config dict into `start_fsp_displays()` and `.started()`-deliver
  both the fsp admin and any volume chart back up to the calling display
  loop code.

ToDo:
- repair `ChartView` click-drag interactions
- auto-range on $ vlm needs to use `ChartPlotWidget._set_yrange()`
- a lot better styling for the $_vlm overlay XD
