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.

the basics work
the sequence has to be a minimum length, 8 entries, but this problem
is not detected. I don't THINK this is an insurmountable problem.

Add initial RP2040 support
The RP2040 is new microcontroller from Raspberry Pi that features
two Cortex M0s and eight PIO state machines that are good for
crunching lots of data. It has 264k RAM and a built in UF2
bootloader too.
