Optimize the Raspberry Pi boot times

[IronOxidizer]

Current boot time is 60s, the goal is 10s, however this can be reduced up to 2s.

This can be done in multiple stages:

1. Optimizing the Raspberry Pi OS Lite image
2. Creating a custom image via Buildroot or Yocto
3. Optimize the custom image + kernel
4. Optimizing the firmware

This line from the "optimize script" seems to break the ability to use the ALT key: https://github.com/beeper/beepberry/blob/6f5fbbbee8f2d785092dc2861c418d496b4a4025/raspberrypi/optimize_boot.sh#L25
