Phil Howard de3ceac4a5 Pico Scroll/Unicorn: Fix static memory alloc for Pico W. 
Pico Scroll and Pico Unicorn were allocating static buffers for gamma and font data respectively.

Make Pico Scroll's `__bitmap` static.

Move Pico Unicorn's three GAMMA tables to one 14-bit table in "pimoroni_common.hpp". Rename "GAMMA" to "GAMMA_8BIT".

Phil Howard 7375a208c6 make GAMMA common 
Moves the 256 entry GAMMA table into pimoroni_common.

Should probably be added into a library so MicroPython is built with only one instance of the table.

Phil Howard e283d460d4 Make ws2812 and apa102 responsibly only for their own buffers 
This fixes a bug where delete[] would be called on a bytearray buffer allocated by MicroPython on gc_heap.

Phil Howard 53429e0c6f Do not pio_sm_unclaim for MicroPython 
Adds an ifdef guard around `pio_sm_unclaim` that prevents it being called when MicroPython cleans up/finalizes classes.

For some reason this appeared to be causing a hardfault.
