Various fixes and improvements (#269)

- Bump version for next release
- Fix default gamma for CYD 2432S032C
- Remember gamma curve setting from Display settings app
- Add UART to Core2 (still has no voltage on Grove port, though)
- LVGL performance improvements: pin to second core and set task priority to "critical"
- Fix build warnings, including deprecations
- Removed deprecated `Thread` constructor
- Fix WaveShare S3 display: Some displays would show a white screen at 12MHz, so I'm putting it back to the
official config values.
