Me Here 111da49b5a PM_K-1 CircuitPython: fix MemoryError + red/blue swap (from on-board test) ...

On hardware the app rendered, beeped and took input, then died with MemoryError at
the text Bitmap alloc — the two ~37KB base64 font strings stayed pinned in RAM. Move
the fonts to small binary files read at boot (font_m.bin / font_l.bin), drop the
base64 + binascii, and gc.collect() before each text bitmap. code.py 56KB -> 20KB and
RAM use drops ~37KB+. Also: cyan rendered as yellow (R/B swapped) -> MADCTL 0x40 -> 0x48.
Bundle + README updated to include the font blobs. (LED still needs the neopixel lib.)
