A GENETIC server with external (import) providers and EOSdash disabled
loads several large packages at start that it never uses, which costs
a noticeable part of the memory on 512 MB boards:
- matplotlib via the GENETIC/GENETIC0 PDF report modules (server/eos.py)
- statsmodels via the Holt-Winters fallback in prediction/priceabc.py
- pvlib via the weather base class and the pvlib-based providers
- bs4/lxml via the ClearOutside provider
- scipy via the self-consumption interpolator singletons, which were
loaded at import time
- the GENETIC0 optimizer, imported by core/ems.py
- tzfpy, whose polygon data the computed general.timezone loads
Import these where they are used. The interpolator tables are loaded
on first use (thread-safe). Nothing changes in what is computed.
general.timezone is computed from latitude/longitude and cannot be set.
Add general.timezone_override (IANA name, validated with pendulum):
when set, general.timezone returns it and the lookup is skipped. When
unset (default) the lookup is unchanged.
Tests that patched the moved names now patch them at their source.
A new test starts the server module in a subprocess and checks that
none of these modules is loaded.

Add a PV forecast provider that calculates the forecast using a PVLib system model
and weather forecast from the EOS weather forecast provider.
Additional module and inverter models can be easily added as the database
is build from PVLib and SAM databases and a bundled csv file.
The module model and inververt model names are provided by new endpoints
to be used in configuration.
The provider is based on the fantastic work of EMHASS. See
https://github.com/davidusb-geek/emhass/blob/master/src/emhass/forecast.py
A short description of the provider is added to the documentation.
Besides the new features there are the fixes and improvements:
* feat: improve EOSdash config page
* fix: kex_to_series for start_datetime
Make key_to_series always start the series at start_datetime.
* fix: default provider for GENETIC and GENETIC0 optimization
To make the default less dependent on internet servers (with API changes and
availability issues) the default for PVForecast is set to PVForecastPVLib
and for ElecPrice to ElecPriceFixed. The default weather provider is changed
to OpenMeteo.
* fix: EOSdash display resampled prediction values
Make EOSdash display resampled prediction values where resampling fits to
the prediction value type. Use bar width that fits to 15 minutes value samples.
* chore: add a UI hints system to EOSdash
The UI hints system eases the definition of forms for configuration items.
There are also forms for items in maps and lists. These forms allow to add and delete
items to/ from maps and lists. The forms ensure that all required fields of newly
added items are filled.
* chore: Create an enum for valid optimization algorithms
* chore. Make config also provide the available energy management modes.
Used for configuration hints.
* chore: Randomize default device id in configuration
