Add initial pixel buffer caching usage
...
Leverages `QGraphicsItem.cacheMode` to speed up interactivity via
less `.paint()` calls (on mouse interaction) and redraws of the
underlying path when there are no transformations (other then a shift).
In order to keep the "flat bar on new time period" UX, a couple special
methods have to be triggered to get a redraw of the pixel buffer when
appending new data.
Use `QPainterPath.controlPointRect()` over `.boundingRect()` since
supposedly it's a lot faster. Drop all use of `QPicture` (since it seems
to conflict with the pixel buffer stuff?) and it doesn't give any
measurable speedup when drawing the "last bar" lines.
Oh, and add some profiling for now.

First draft, make graphics work on shm primary index

This is a bit hacky (what with array indexing semantics being relative
to the primary index's "start" value but it works. We'll likely want
to somehow wrap this index finagling into an API soon.

Attempt to add numba typing and use `QGraphicsPathItem`
...
Failed at using either.
Quirks in numba's typing require specifying readonly arrays by
composing types manually.
The graphics item path thing, while it does take less time to write on
bar appends, seems to be slower in general in calculating the
``.boundingRect()`` value. Likely we'll just add manual max/min tracking
on array updates like ``pg.PlotCurveItem`` to squeeze some final juices
on this.

Get `QPainterPath` "append" working
...
Pertains further to #109 .
Instead of redrawing the entire `QPainterPath` every time there's
a historical bars update just use `.addPath()` to slap in latest
history. It seems to work and is fast. This also seems like it will be
a great strategy for filling in earlier data, woot!
