A bunch of minor updates, and some big internal changes to make the code nicer to work with:
- DIO mode updated to change pin states simultaneously
- LED APA102: fix start/stop frame. Force the first 8 bits (0b111 + global brightness) high.
- LED WS2812: fix reset delay
- FALA buffer overrun detect and alert
- All mode commands updated to handle FALA gracefully internally
- Most modes have been verified to work with FALA
- New global and mode command structs make code more readable
