Confirm all USB modules

[Frijol]

Ensure we have recommended USB module (vendor), npm package, and any necessary documentation for every planned USB module.

• Camera
• Bluetooth low energy
• Cellular modem
• Audio
• Storage

I'm going to write this out here, but we can migrate the content later.

Camera + Audio: both of these will be served by the "audiovideo" module which serves to do both video/audio recording/playback. ("Video playback" is a non-issue for Tessel, but may be useful outside of Tessel)

BLE: we will be using "noble". Noble has poor Windows support, because Windows has poor BLE support.

Cellular: this is actually just a small extension to tessel's ap/sta functionality. It requires some additional support. Track on tessel/cli

Storage: track on tessel/cli what we do about auto-booting. We also probably want a library or examples about detecting and iterating through storage endpoints, since in general we won't be writing to the OpenWRT fs.

Ok. There is a space for each of these within the modules.json, so a PR would be helpful for ones that are finished. And then technical-io needs to show packages for USB modules, which I can work on

Here is a write up on using BLE over USB from a while back:
