Tyler Goodlet 3670184c18 Bleh, try a bunch of stuff for step filling
Turns out the performance of updating and refilling step curves > 1k ish
points is super slow :sadkek:. Disabling the fill basically returns
normal performance, so it seems maybe we'll stick with unfilled volume
"bars" for now. The other tricky bit is getting the path to extend and
fill which is particularly slow if you use the `QPainterPath.united()`
(what `+` set op does) operation which seems to require an entire redraw
of the curve each paint iteration. Removing the pixel buffer cache makes
things that much worse too..

One technique i tried was only setting a `._fill` flag when so many
datums are in view (< 1k as determined by the chart widget), and this
helps, but under high load (trade rates) you still see more lag then
without the fill which makes me say screw it and let's stick with
unfilled bars for now. Trying go to get performant filled curves will be
an exercise for an aspiring graphics eng :P

Tyler Goodlet 168c1eb2a9 Add volume plot as default
Toss in support for a "step mode" curve (unfinished atm) and use it to
plot from the `volume` field of the ohlcv shm array (if available).

changes to make it happen,
- dynamically generate the fsp sidepane form from an input config `dict`
  |_ dynamically generate the underlying `pydantic` model
  |_
- add a "volume checker" helper func that inspects the shm array
- toss in sidepane resize calls to avoid race where the ohlcv array
  is plotted too slowly compared to the volume and the chart somehow
  doesn't show..
- drop duplicate rsi2 cruft (previously used to test plots of the shm
  data)

Tyler Goodlet 699e670363 Invert 'c' (connection) array
In latest `pyqtgraph` it seems there's a discrepancy
since `function.arrayToQPath()` was reworked and now
we need to *not* connect the last point for each bar.

Tyler Goodlet 3dd82c8d31 Fix the drunk fix
This should finally be correct fsp src-to-dst array syncing now..
There's a few edge cases but mostly we need to be sure we sync both
back-filled history diffs and avoid current step lag/leads. Use
a polling routine and the more stringent task re-spawn system to get
this right.

Tyler Goodlet 2b9fb952a9 Fix shm index update race
There was a lingering issue where the fsp daemon would sync its shm
array with the source data and we'd set the start/end indices to the
same value. Under some races a reader would then read an empty `.array`
which it wasn't expecting. This fixes that as well as tidies up the
`ShmArray.push()` logic and adds a temporary check in `.array` for zero
length if the array hasn't been written yet.

We can now start removing read array length checks in consumer code
and hopefully no more races will show up.

Tyler Goodlet 2cd594ed35 Add profiling to fsp engine
Litter the engine code with `pyqtgraph` profiling to see if we can
improve startup times - likely it'll mean pre-allocating a small fsp
daemon cluster at startup.
