Add a driver for the Waveshare 2.7in V1 e-Paper HAT. This panel uses an IL91874-style controller, different from the IL3820 and SSD1680 controllers used by the other panels in this package. The controller also needs a GET_STATUS command before each BUSY read, or the BUSY pin never updates. Add a slideshow example for the Waveshare RP2040-PiZero. Each picture is a packed 1 bit per pixel asset file under assets/, embedded with go:embed, and the firmware cycles through the files in name order, one image every 10 seconds. The scaffold ships with four public domain pictures, dithered to 1 bit: the 1984 Macintosh hello screen, The Great Wave off Kanagawa, a 1972 Soviet space era stamp, and a guinea pig photo. Verified on real hardware: RP2040-PiZero with the 2.7in V1 HAT on the standard 40 pin header.
