Update Torquetuner repository

[aburt2]

Add new torquetuner design and firmware to IDMIL torquetuner repository

[aburt2]

@ChristianFrisson ready to merge, updating the public repo with all the changes and updates we made to Torquetuner including the new firmware and hardware and some build guides

[ChristianFrisson]

@aburt2 Excellent! Great work! Many updates!

Instead of commit add firmware and hardware from gitlab, remove git submodules, I think we should keep software dependencies as git submodules, but update them to the relevant sources, ie Moteus instead of Mechaduino-Firmware and a new mirror of TorqueTuner-ESP32 on IDMIL's github. What do you think about this?

(I can help do that if you need.)

[aburt2]

I guess we can do that, I don't have much experience with git submodules so I would need help with setting that up

[ChristianFrisson]

Alright I'll prepare another pull request using your branch with commit e2247e2 rebased to use git submodules instead of copied files.
