a32337718d Rename _protomatter -> protomatter 
I originally believed that there would be a wrapper library around it,
like with _pixelbuf; but this proves not to be the case, as there's
too little for the library to do.

3a94412cd3 protomatter: more memory allocation fixes 
- bump supervisor alloc count by 4 (we actually use 5)
 - move reconstruct to after gc heap is reset
 - destroy protomatter object entirely if not used by a FramebufferDisplay
 - ensure previous supervisor allocations are released
 - zero out pointers so GC can collect them

Add polarity and phase to FourWire. 
It was fixed as 0/0 even though it used to get it from the current
SPI state. This makes it more explicit with kwargs.

449dbea456 Mixer: Rework for performance, particularly of the S16 case 
This removes downscaling (halving-add) when multiple voices are
being mixed.  To avoid clipping, and get similar behavior to before,
set the "level" of each voice to (1/voice_count).

Slow paths that were applicable to only M0 chips were removed.

As a side effect, the internal volume representation is now 0 ..
0x8000 (inclusive), which additionally makes a level of exactly 0.5
representable.

Testing performed, on PyGamer: For all 4 data cases, for stereo and
mono, for 1 and 2 voices, play pure sign waves represented as
RawSamples and view the result on a scope and through headphones.
Also, scope the amount of time spent in background tasks.

Code size: growth of +272 bytes

Performance (time in background task when mixing 2 stereo 16-bit voices):
76us per down from 135us (once per ~2.9ms long term average)
(Decrease from 4.7% to 2.4% of all CPU time)
