Chris Blume 9e788f7379 Correct Pico Display 2 baud 
The Pico Display 2 example specifies a baud of 74 * 1000 * 1000.
However, the highest baud the Raspberry Pi Pico can achieve is
62,500,000.

I checked and even when the baud of 74 * 1000 * 1000 is specified,
it ends up using the max that the Raspberry Pi Pico can handle anyway.

This commit removes the incorrect baud parameter, using the default
parameter instead.

Phil Howard 4d33649cd2 HUB75: More rational DMA/PIO setup/teardown, fixes reset bug 
Defensively tear down DMA/PIO so it's in a known good state upon (soft)reset.

Issue was a race condition with DMA interrupts firing and not being achknowledged, leaving a stuck raised IRQ.

The blocking wait for DMA transactions also exacerbated this, turning a borken DMA interrupt and blank screen into an unrecoverable hardlock.

...not that the blank screen was recoverable without a soft reset anyway!

Phil Howard 30a455a9d5 HUB75 Less RAM, DMA flip 
Switch from 12-bit to 10-bit gamma to fit RGB into a uint32_t. Simplifies PIO and halves the RAM usage for F/B buffer.

Switch "flip" to *literally* swap the front and back buffers, and then asyncronously DMA the new back buffer into the front ready for the next draw.

Phil Howard eed7992127 HUB75 Fix intermittent display corruption issue 
The FM6126A register write was causing some weirdness on soft reset where the pin state wasn't predictable.

Have twiddled some pins at startup to ensure everything works as expected.

Add set_hsv and set_all_hsv (since setting individual pixels with hsv is S L O W)

Made "flip()" blocking, it was easy to accidentally get a little tearing.

TODO:

* Move this into drivers for C++ use too
* Fix hitting "Stop" in Thonny causing rows to stick on the display (this is bad, and should not happen)
* Fix "Stop -> Start" in Thonny causing weird display issues (it's not memory offets, maybe DMA/PIO issues?)
