* implements UI to configure battery discharge limit
* adds support for discharge limit to MQTT battery provider
* add option to hide `issues` section from battery live view (for MQTT battery)
this changeset adds support for parsing the MQTT battery provider's SoC
and voltage topics' payloads as JSON to extract a numeric value at a
configurable path.
* fix compiler warning in SerialPortManager.cpp: function must not
return void
* clean up and simplify implementation of usesHwPort2()
* make const
* overrides are final
* default implementation returns false
* implement in header, as the implementation is very simple
* rename PortManager to SerialPortManager. as "PortManager" is too
generic, the static instance of the serial port manager is renamed to
"SerialPortManager". the class is therefore renamed to
SerialPortManagerClass, which is in line with other (static) classes
withing OpenDTU(-OnBattery).
* implement separate data ages for MPPT charge controllers
* make sure MPPT data and live data time out
* do not use invalid data of MPPT controlers for calculations
* add :key binding to v-for iterating over MPPT instances
this change adds support for a second Victron MPPT charge controller
using a second serial connection.
* Add device configuration for a second victron mppt
* Update VedirectView for second victron mppt
* Update MqttHandleVedirect for second victron mppt
* Update MqttHandleVedirectHass for second victron mppt
* Handle nonexisting victron controllers with optionals
* Add bool-function to Battery and inherited classes, if uart port 2 is
being used
* Introduced a serial port manager. In order to prevent the battery and
the Victron MPPT to use the same hw serial ports, this class keeps
track of the used ports and their owners.
the Victron SmartShunt communicates the SoC value in permille. this
should be displayed in the web UI accordingly. this is a good excuse to
fully move ownership of the SoC value to the BatteryStats base class and
add a precision indicator variable. this is required to be set each time
a derived class (a battery provider) wants to update the SoC value. the
precision is then used when populating the JSON data for the web UI
(live view).

this extends the MqttBattery implementation by an additional topic which
allows to subscribe to receive battery voltage readings through the MQTT
broker. similar to the battery SoC topic, this allows to import a
critical battery data point for the DPL, in case the user chooses to use
voltage thresholds rather than SoC thresholds to control the DPL. if an
otherwise incompatible BMS is available which publishes the battery pack
voltage through MQTT, this can now be used to feed accurate voltage
readings to the DPL.
this battery provider implementation subscribes to a user-configurable
MQTT topic to retrieve the battery SoC value. the value is not
re-published under a different topic. there is no card created in the
web app's live view, since the SoC is already part of the totals at the
top of the live view. that is the only info this battery provider
implements.
