Tyler Goodlet 9c57f10e77 Make pause/resume feed methods sync again
We can instead use the god widget's nursery to schedule all the feed
pause/resume requests and be even more concurrent during a view (of
symbols) switch.

Use `tractor.trionics.gather_contexts()` to start up the fsp and volume
chart-displays (for an additional conc speedup). Drop `dolla_vlm` again for
now until we figure out how we can display it *and* vlm on the same
sub-chart? It would be nice to avoid having to spawn an fsp process
before showing the volume curve.

Tyler Goodlet 644ac6661c Fix sidepane alignment with FSP charts
Call the resize method only after all FSP subcharts have rendered
such that the main OHLC chart's final width is read.

Further tweaks:
- drop rsi by default
- drop the stream drain stuff
- fix failed-to-read shm logging

Tyler Goodlet 56b65a1cde Make chart switching super fast again
This fixes a weird re-render bug/slowdown/artifact that was introduced
with the order mode sidepane work. Prior to the sidepane addition, chart
switching was immediate with zero noticeable widget rendering steps.

The slow down was caused by 2 things:
- not yielding back to the Qt loop asap after re-showing/focussing
  a linked split chart that was already in memory.
- pausing/resuming feeds only after a Qt loop render cycle has
  completed.

This now restores the near zero latency UX.

Tyler Goodlet 9951e1d4c9 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.

Revert to old shm "last" meaning last row

Tyler Goodlet 4c9e5feace Expose dollar volume to fsp engine
It can now be declared inside an fsp config dict under the name
`dolla_vlm`. We still need to offer an engine control that zeros
the newest sample value instead of copying from the previous.

This also litters 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.

Tyler Goodlet 224c01e43e Spawn and cache an fsp cluster ahead of time
Use a fixed worker count and don't respawn for every chart, instead
opting for a round-robin to tasks in a cluster and (for now) hoping for
the best in terms of trio scheduling, though we should obviously route
via symbol-locality next. This is currently a boon for chart spawning
startup times since actor creation is done AOT.

Additionally,
- use `zero_on_step` for dollar volume
- drop rsi on startup (again)
- add dollar volume (via fsp) along side unit volume
- litter more profiling to fsp chart startup sequence
- pre-define tick type classes for update loop
