Tyler Goodlet 4c7661fc23 Factor `.update_from_array()` into `Flow.update_graphics()`
A bit hacky to get all graphics types working but this is hopefully the
first step toward moving all the generic update logic into `Renderer`
types which can be themselves managed more compactly and cached per
uppx-m4 level.

Tyler Goodlet 1dca7766d2 Add notes about how to do mkts "trimming"
Which is basically just "deleting" rows from a column series.
You can only use the trim command from the `.cmd` cli and only with a so
called `LocalClient` currently; it's also sketchy af and caused
a machine to hang due to mem usage..

Ideally we can patch in this functionality for use by the rpc api
and have it not hang like this XD

Tyler Goodlet 5d294031f2 Factor step format data gen into `to_step_format()`
Yet another path ops routine which converts a 1d array into a data
format suitable for rendering a "step curve" graphics path (aka a "bar
graph" but implemented as a continuous line).

Also, factor the `BarItems` rendering logic (which determines whether to
render the literal bars lines or a downsampled curve) into a routine
`render_baritems()` until we figure out the right abstraction layer for
it.

Tyler Goodlet 9c5bc6deda Add `.ui._pathops` module
Starts a module for grouping together all our `QPainterpath` related
generation and data format operations for creation of fast curve

it to a new `._pathops.xy_downsample()`.

Tyler Goodlet 47cf4aa4f7 Error log brokerd msgs that have `.reqid == None`
Relates to the bug discovered in #310, this should avoid out-of-order
msgs which do not have a `.reqid` set to be error logged to console.
Further, add `pformat()` to kraken logging of ems msging.

Tyler Goodlet 186658ab09 Drop uppx guard around downsamples on interaction
Since downsampling with the more correct version of m4 (uppx driven
windows sizing) is super fast now we don't need to avoid downsampling
on low uppx values. Further all graphics objects now support in-view
slicing so make sure to use it on interaction updates. Pass in the view
profiler to update method calls for more detailed measuring.

Even moar,
- Add a manual call to `.maybe_downsample_graphics()` inside the mouse
  wheel event handler since it seems that sometimes trailing events get
  lost from the `.sigRangeChangedManually` signal which can result in
  "non-downsampled-enough" graphics on chart given the scroll amount;
  this manual call seems to entirely fix this?
- drop "max zoom" guard since internals now support (near) infinite
  scroll out to graphics becoming a single pixel column line XD
- add back in commented xrange signal connect code for easy testing to
  verify against range updates not happening without it

Tyler Goodlet 12d60e6d9c WIP get incremental step curve updates working
This took longer then i care to admit XD but it definitely adds a huge
speedup and with only a few outstanding correctness bugs:

- panning from left to right causes strange trailing artifacts in the
  flows fsp (vlm) sub-plot but only when some data is off-screen on the
  left but doesn't appear to be an issue if we keep the `._set_yrange()`
  handler hooked up to the `.sigXRangeChanged` signal (but we aren't
  going to because this makes panning way slower). i've got a feeling
  this is a bug todo with the device coordinate cache stuff and we may
  need to report to Qt core?
- factoring out the step curve logic from
  `FastAppendCurve.update_from_array()` (un)fortunately required some
  logic branch uncoupling but also meant we needed special input controls
  to avoid things like redraws and curve appends for special cases,
  this will hopefully all be better rectified in code when the core of
  this method is moved into a renderer type/implementation.
- the `tina_vwap` fsp curve now somehow causes hangs when doing erratic
  scrolling on downsampled graphics data. i have no idea why or how but
  disabling it makes the issue go away (ui will literally just freeze
  and gobble CPU on a `.paint()` call until you ctrl-c the hell out of
  it). my guess is that something in the logic for standard line curves
  and appends on large data sets is the issue?

Code related changes/hacks:
- drop use of `step_path_arrays_from_1d()`, it was always a bit hacky
  (being based on `pyqtgraph` internals) and was generally hard to
  understand since it returns 1d data instead of the more expected (N,2)
  array of "step levels"; instead this is now implemented (uglily) in
  the `Flow.update_graphics()` block for step curves (which will
  obviously get cleaned up and factored elsewhere).
- add a bunch of new flags to the update method on the fast append
  curve:  `draw_last: bool`, `slice_to_head: int`, `do_append: bool`,
  `should_redraw: bool` which are all controls to aid with previously
  mentioned issues specific to getting step curve updates working
  correctly.
- add a ton of commented tinkering related code (that we may end up
  using) to both the flow and append curve methods that was written as
  part of the effort to get this all working.
- implement all step curve updating inline in `Flow.update_graphics()`
  including prepend and append logic for pre-graphics incremental step
  data maintenance and in-view slicing as well as "last step" graphics
  updating.

Obviously clean up commits coming stat B)

Tyler Goodlet b97ec38baf Always maybe render graphics
Since we have in-view style rendering working for all curve types
(finally) we can avoid the guard for low uppx levels and without losing
interaction speed. Further don't delay the profiler so that the nested
method calls correctly report upward - which wasn't working likely due
to some kinda GC collection related issue.
