previously, the Pytlontech Home Assistent class implementation had an
init() method, that was never called, as it did nothing. the class
relied on its loop() method being called from the main loop(). after
switching to the TaskScheduler approach, the Pylontech Home Assistent
class init() method was adjusted to register a task that calls the
loop() method periodically. however, the init() method was still not
called.
currently the whole SmartShunt data structure is copied to the
BatteryStats instance in every loop, even though the data cannot
possibly have changed. this is quite an expensive task to do in every
loop. this change tracks the last update timestamp and only does the
copy operation if an actual updated data structure was received from
the smart shunt.
this change adds the values of ESP.gteMaxAllocHeap() and
ESP.getMinFreeHead() to the prometheus metrics and the system
information object. the web UI uses these values to diplay the size of
the largest free contiguous block, calculate a rough estimate for the
level of fragmentation, and the maximum usage of heap memory since boot
in absolute and relative amounts.

OpenDTU console gets spammed with "WifiGeneric::hostByName() error when first trying to resolve the hostname via DNS. So reverse order: first try mDNS, if that fails try DNS. Also ensure that https bool is passed correctly to HTTPClient::begin(). Lastly, concatenate strings for building Digest authorization using "+" and not via snprintf.
this change utilizes some of the features from library "frozen", which
was included upstream for the grid profile parser. to improve code
maintainability, a couple of std::maps mapping strings to values or the
other way around were introduced in OpenDTU-OnBattery-specific code at
the expense of some flash and computing overhead.
library "frozen" offers constexpr versions of map and string, which
saves initialization code and offers slightly faster lookups. this
brings the binary size down by ~25kB and should provide a small
performance improvement at runtime.
Added ability to deal with local host names (mDNS), remove use of FirebasedJson to save ~20kB build size, some changes to PowerLimiter to avoid setting new inverter power limits when not needed (=current limit as reported by inverter is within hysteresis)
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.
