the DPL already took care to shut down the inverter if anything fishy
was going on, mainly to make sure that the battery is not drained.
however, some cases were missed:
* if the configuration changed such that another inverter is now
targeted, the one the DPL controlled previously was not shut down.
* if the configuration changed such that another inverter (different
serial number) was configured at the same index, the previous one
was not shut down.
this change corrects these problems by making the DPL keep a copy of the
shared_ptr to the inverter. the shared_ptr is only released once the DPL
shut the respective inverter down.
this implementation checks all requirements for a new power limit to be
calculated, one after the other. if any requirement is not met, a
respective status is announced.
status messages are communicated on the (serial) console. these can also
be displayed easily on the web app in the future. the status texts
explain clearly what the DPL is currently doing, which aids
understanding how the DPL works. the status is only announced if it
changes, or after a fixed interval.
as each requirement is checked individually, the code readability is
improved as well. previously, all the respective conditions had to be
checked as well, but the statements were more complex.
the DPL loop is now executed with high frequency, i.e., it does not wait
for a fixed timespan to pass before checking requirements. it always
aborts on the first unmet requirement. this should improve responsiveness,
as the DPL checks all requirements more often.
the DPL now waits for all power commands and power limit updates to
complete. when that is the case, a settling time elapses. after the
settling phase, the DPL waits for a new update from the inverter and
from the power meter. now it can be assumed that the values are in sync.
it then makes sense to calculate a new power limit immediately, which
the DPL then does.
the defaults for solar passthrough voltage thresholds shall be floats,
so the user can store float values to the config. otherwise, float
values can and will be stored, but when reading them, the defaults will
be applied as the defaults are of an incompatible type.
there is no need to assume and hardcode a fixed efficiency for the
Victron solar charger. the charger reports the voltage and current at
its battery terminal, which can be used to calculate the charger's
actual power output.
the fallback to 100% for the efficiency of the Hoymiles inverter, in
case it is not producing power, is too optimistic. this commit proposes
to use 96.7% as the efficiency for that case, which is the peak
efficiency for many (all?) Hoymiles inverters as per datasheet. that
value should be closer to the real efficiency that will be achieved once
the inverter is turned on.
In addition to the cyclic query of the power meters, they will be queried on demand when total power is requested and last update is older than 1 second.

* add support for energy & power readings on SML based power meters, taking OBIS 16.7.1 for power (using mod. SML Parser lib. by olliiiver)
* switched SML read to use software serial
* made total power meter response controled by meter source to obtain either the sum of phase powers or explicit total power provided by meter
* made mqtt subscriptions to power meter topics meter source dependend
* simplified SML read loop and OBIS handler registration, + minor refactoring
* minor cleanup/style changes and optim. PowerMeter
* fixed build, add SOURCE_SML == 4
* removed optional usage of HW serial for SML power meter
* switched to usage of _powerMeter1Power for SML power reading to allign better with existing code
