Feature request: allow switching between 1-phase and 3-phase charging via API

[thmjanssen]

Per the title. :)
Allow home automation software to switch between 1-phase and 3-phase charging. Expected behaviour would be a new session would start on the set number of phases. A currently active charging session would be stopped and started again but now with the different # of phases.

That is already in there: You can set the C2 contactor through enable_C2 via the API.

Better switch to v3.6.1, this repo is deprecated.
