pmowandClaude Opus 5.5 da5ff56cff feat(eink): bulk SPI row writes for the GDEQ0426T82, at 8 MHz ...

GxEPD2 sends the panel RAM a byte at a time; on the nRF52's SPIM the
per-call overhead dominates, and an 800x480 partial refresh writes the
whole 48 KB several times. GxEPD2_426_GDEQ0426T82_Fast overrides the three
image writes to send each row in one transfer() call, falling back to the
stock path for the cases it doesn't cover (first write, mirror_y, PROGMEM).
Byte-for-byte the same data as the stock driver.

Opt-in per env: -D EINK_FAST_WRITES=1, and EINK_SPI_HZ (default 4 MHz,
8 MHz here, SPIM2's ceiling).
