* add calculated values to VE.Direct data
solar current, battery output power, and the charger's efficiency can be
calculated from the values reported by the charger. the efficiency must
be taken with a grain of salt. it seems that the solar power value and
the battery output voltage/current are not always in sync. for that
reason a moving average is used to smooth out the calculated efficiency
value.
* show calculated VE.Direct values in web live view
order the values and translations similarly for the input and output,
starting with power at the top, then voltage, then current as the last
of these three.
* VE.Direct live view: use 'd' as unit for days
'd' is the SI unit symbol for days and does not need translation, which
is desirable as units are not translated throughout the project.
* refactor VE.Direct live view
* move Dynamic Power Limiter data into its own type.
* split VE.Direct data into three types: "device", "input", and
"output". hence all input and output values are now ValueObject, which
allows to iterate over them using a loop without typing issues.
* generate the tables with input and output values using a loop, rather
than defining each row individually.
* localize numbers using $n (vue method), which fixes switching the
number format (dot vs. comma) when switching the language.
* use no decimal point for power values (they are integers), three
decimal points for kWh values (charger only reports two decimal
places, but three are easier to read since the unit is *kilo* Wh), one
decimal point for the efficiency, and two for voltage and current.
* update language tokens to avoid mapping JSON keys to language keys
(use the JSON keys to access the language tokens).
* re-structure language tokes so the brief keys took over from
VeDirectFrameHandler always make sense (nest into "input" and
"output").
* order values similarly from top to bottom: power, then voltage, then
current. this is following the order of the inverters' details.
* group values by type/unit (yield and max. power) and order them
"newest" to "oldest" from top to bottom.
* increase the DynamicJsonDocument as it was too small to hold the newly
added data.
* update webapp_dist to include VE.Direct live view refactoring
