📄 Description

This PR touches a LOT more files than I expected! Feedback is solicited and more than welcome!

Change summary:

  1. Coprocessor OTAU now downloads images from the configured repo.
  2. The coprocessor firmware version is now reported when updates screen is opened and after updating.
  3. Support for updating the Lilygo T-panel's H2 coprocessor was added.

This PR also lays a lot of ground work for eventual OTA for other coprocessors such as the TLSR.

A Beta release is available testing. The Beta's user orientated installation instructions include screen captures of the changed screens for easy review of the changes.

I have done extensive testing and have seen two issues I haven't been able to reproduce enough to debug. Perhaps some extra eyes and "extreme programming" will help find them.

  1. While flashing heap corruption is detected and the AP reboots.
  2. Downloads hang without reporting an error.

The first issue hasn't occurred recently and I have no idea for how to reproduce it. I've been monitoring the amount of unused stack space after an successful flash and I don't think that's the issue.

I can simulate download failures and will continue to try to debug the second issue when I get time.

These issues occur less than 10% of the time and they always resulted in a successful reboot and successful update after a retry.

I believe the benefits of the PR outweighs the risk, particularly if the Lilygo T-panel catches on.
