Battery Voltage

Readout/monitor battery voltage and turn off in case it gets too low. Also make the voltage available via API.

Partly implements #34.

added 3-Epicardium 3-Module labels

Looks good to me! Thanks for keeping our codebase clean.

However, I'm only a bot - so a human will still have to approve this request.

@schneider, the implementation is now complete, apart from it only ever reading 3.22 V. If you can give me pointers where this comes from, I can try digging into it.

I'd like to wait with this until we have the voltage reading sorted out. Can you reproduce the value with the prototype or is this something which has changed with production hardware?

I have only tested it with the prototype hardware (new harmonic board though).

@schneider, if you have a few minutes tomorrow (today?) in the morning, could you take a quick look whether this is a good battery protection implementation?
