Stop the flickering vertical stripes on the CYD panel (0.2.49)

The cheap ILI9341 panel showed a fine vertical line pattern that shimmered
when you moved your eyes or the board. Frame inversion (0xB4 0x07) at the
panel's highest frame rate (0xB1 0x00 0x10) removes it; VCOM stays default.
Firmware 0.2.42 for both boards, version only on the Guition.

+- **CYD panel fix.** The cheap 2.8" panel showed a fine pattern of vertical lines that shimmered when you moved your eyes or the board. The screen now uses frame inversion at the panel's highest refresh rate, which removes the stripes. Colours and contrast are unchanged. Guition screens are not affected.
+- Firmware 0.2.42 for both boards (version only on the Guition); the app offers the update.
+
 ## 0.2.48 (firmware 0.2.41)
 
 Keep a screen awake from a Home Assistant automation.
