Integration of Victron SmartShunt via VE.Direct (#452)

* Move Mppt logic to subclass

* Added Definitions for Shunts and restructering

* First integration of SmartShunt data into Web Interface

* Code cleanup

* VE.Direct: whitespace cleanup

* VE.Direct: manage HardwareSerial in unique_ptr

* VE.Direct: _efficiency is only needed by MPPT

* VE.Direct: keep as many members private as possible

* VE.Direct: use int8_t for pins (as before)

* VictronSmartShunt: _verboseLogging is not used

* VE.Direct: OR (off reason) is MPPT specific

it also applies to Phoenix inverters and Smart BuckBoost, but since
there is no support for those, the code is moved to the MPPT controller.

* Added Shunt alarms to liveview
Changed from double to int for several readings

* Update build.yml to allow manual builds
