Jeff Epler b7f5c277ad _pixelbuf: Increase performance of brightness-scaling 
On the Pico, this increases the "fill rate" of
    pixels[:] = newvalues
considerably.  On a strip of 240 RGB LEDs, auto_write=False, the timings
are:

|| Brightness || Before || After || Improvement ||
|| 1.0        || 117 kpix/s || 307 kpix/s || 2.62x ||
|| 0.07       || 117 kpix/s || 273 kpix/s || 2.33x ||

It's worth noting that even the "before" rate is fast compared to the
time to transmit a single neopixel, but any time we can gain back
in the whole pipeline will let marginal animations work a little better.
To set all the pixels in this way and then show() gives a pleasant bump
to the framerate, from about 108Hz to 124Hz (1.15x)

The main source of speed-up is using integer math instead of floating
point math for the calculation of the post-scaled pixel values.  A slight
secondary gain is achieved by avoiding the scaling altogether when
the scale factor is 1.0.

Because the math is not exactly the same, some scaled pixel values may
change by +- 1 RGBW "step".  In practice, this is unlikely to matter.

The gains are bigger on the Pico and other M0 microcontrollers than M4
microcontrollers with floating point math in the hardware.

Happily, flash size is also improved a bit on the Pico build I did,

Add state machine divisor check 
This causes an exception when setting a state machine too slow or
too fast.

Implement audiobusio and enhance PIO for it 
This adds I2SOut and PDMIn support via PIO.

StateMachines can now:
 * read and read while writing
 * transfer in 1, 2 or 4 byte increments
 * init pins based on expected defaults automatically
 * be stopped and restarted
 * rxfifo can be cleared and rxstalls detected (good for tracking when
   the reading code isn't keeping up)

Fixes #4162

Jeff Epler 144acfcb98 USB descriptors: Save flash storage for serial number 
This saves about 60 bytes (Feather M4 went from 45040 -> 45100 bytes free)
66 bytes of data eliminated, but 6 bytes paid back to initialize the length
field.
