Over-The-Air (OTA) Update Library

[vzahradnik]

Is your feature request related to a problem? Please describe.
A common scenario when developing an embedded hardware are firmware updates. I believe having an abstraction library in TcMenu which does that with different boards would be a great addon to the ecosystem. Especially the commercial users need this feature.

Describe the solution you'd like
I would like to have a one-click solution to add OTA for my target platform. Two modes should be supported:

• Server mode (default) where the embedded board runs a webserver allowing to push an updated firmware
• Client mode where the board could check a remote server for the firmware updates. The exact procedure how would have to be defined.

We can get inspiration from an open Tasmota ESP32 firmware which already has this feature implemented.
