avoid staleness in case the same power limit is calculated over and over
again, hence no new power limit value is calculated and hence no power
limit command is sent to the inverter. staleness occurs in this case if
the first power limit command to establish the respective limit was not
received by the inverter. one can easily simulate a situation where the
same power limit is caluclated over and over again: with a battery above
the start threshold, set a very low upper power limit for the inverter
(DPL setting). that value will be used as the limit as long as the power
meter reading is larger than that.
we could also check the limit reported by the inverter. however, that
value is in percent of the inverter's max AC output, and is often not
the same value as we requested as the limit, but slightly off. we then
would have to decide how much deviation is okay, which is unreasonably
complicated.

Sunrise and -set must recomputed if one of the following conditions is met:
* The date changed (based on the selected timezone)
* Location (Lat/Lon) changed
* Sunset type changed
So instead of calculating that every minute just do it on update via web interface or date change.
If a new config is uploaded, the DTU gets restarted. There is no need to initiate a recalculation in this case.
* VE.Direct MPPT MQTT: remove trailing whitespace
* VE.Direct MPPT MQTT: publish P, IPV and E to MQTT
those values are calculated by OpenDTU-OnBatery and are part of the web
application live view, but were previously not published through MQTT.
closes#376.
* 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

for the MQTT integration, JkBms::DataPointContainer::updateFrom() was
changed such that the data points timestamp reflects the last change of
the data point value. that timestamp was used to set the SoC last update
timestamp. however, that timestampt must reflect the last time the SoC
was successfully received from the JK BMS so we could make sure the
value was up to date.
* JK BMS: avoid trailing whitespace in debug output
* JK BMS: publish data points through MQTT
* JK BMS: updateFrom: skip data points with equal value
this changes the interpretation of the timestamp in data containers that
are merely updated from other data containers: this is the oldest
timestamp known where the value was as recorded by the data point in its
respective container.
the data container constructed from an answer will -- naturally -- have
the timetamps of its data points set to the time they were constructed.
* JK BMS: only publish changed values to MQTT broker
all values are still published once every minute if the MQTT retain flag
is NOT set. otherwise, the constant values are only published once on
startup.

this avoids the debug buffer being overrun if verbose logging is
disabled in particular. that would happen because the buffer would
only be reset if verbose logging was enabled but filled in any case.
