Have start and end kwargs respect element size 
The comment says it is `buffer[start:end]` but it assumed elements
were a single byte long. Now it correctly does multibyte elements
from array.array.

Tweak black_bindings 
Originally, black_bindings found each contiguous "//|" block and sent
it to black independently. This was slower than it needed to be.

Instead, swap the comment prefix: when running black, take off
"//|" prefixes and put "##|" prefixes on all un-prefixed lines.
Then, after black is run, do the opposite operation

This more than doubles the overall speed of "pre-commit run --all",
from 3m20s to 55s CPU time on my local machine (32.5s to under 10s
"elapsed" time)

It also causes a small amount of churn in the bindings, because
black now sees enough context to know whether one 'def' follows another
or ends the 'def's in a 'class'. In the latter case, it adds an extra
newline, which becomes a "//|" line.

I'm less sure why a trailing comma was omitted before down in
rp2pio/StateMachine.c but let's roll with it.

Revamp background writing 
Now a 'once' and a 'loop' buffer can be specified.

'once' is useful for things like writing a neopixel strip in the background,
if you can guarantee the buffer contents are stable until the write is complete.

'loop' is useful for periodic things, like pwm & servos.

both together are useful for some special cases of pwm/servo, where a
transitional waveform needs to be played for one repetition and then
a new waveform needs to be played after that.

The API is renamed to reflect that it's a more generic 'background'
operation.
