Fix for timestamps of 1 minute / 10 minute data provided by DWD

• [FIX] Add missing positional dataset argument for _create_empty_station_parameter_df
• [FIX] Timestamps of 1 minute / 10 minutes DWD data now have a gap hour at the end of year 1999
  due to timezone shifts

Start migrating from dogpile.cache to filesystem_spec

Query specific parameters from dataset

Added

• Enable selecting a parameter precisely from a dataset by passing a tuple like [("precipitation_height", "kl")] or
  [("precipitation_height", "precipitation_more")], or for cli/restapi use "precipitation_height/kl"
• Test of restapi with recent period

Fixed

• Bug when querying an entire DWD dataset for 10_minutes/1_minute resolution without providing start_date/end_date,
  which results in the interval of the request being None
• Get rid of pandas performance warning from DWD Mosmix data

Fix radar

• Bugfix acquisition of DWD radar data
• Adjust DWD radar composite parameters to new index

Bugfix tidy method for DWD observation data

• Bugfix tidy method for DWD observation data

Bugfix show method

• Update readme on sandbox developer installation
• Fix show method

New cli base, fixed InfluxDB export

• Change cli base to click
• Add support for wetterdienst core API in cli and restapi
• Export: Use InfluxDBClient instead of DataFrameClient and improve connection handling with InfluxDB 1.x
• Export: Add support for InfluxDB 2.x
• Fix InfluxDB export by skipping empty fields
• Add show() method with basic information on the wetterdienst instance

Fix DWD Mosmix generator

• Make tidy method a abstract core method of Values class
• Fix DWD Mosmix generator to return all contained dataframes

Add units

• Add origin and si unit mappings to services
• Use argument "si_units" in request classes to convert origin units to si, set to default
• Improve caching behaviour by introducing optional WD_CACHE_DIR and
  WD_CACHE_DISABLE environment variables. Thanks, @meteoDaniel!
• Add baseline test for ECCC observations
• Add DWD Observation hourly moisture to catalogue

Merge with wetterdienst-ui

• Add capability to export data to Zarr format
• Add Wetterdienst Explorer UI. Thanks, @meteoDaniel!
• Add MAC ARM64 support with dependency restrictions
• Radar: Verify HDF5 responses instead of returning invalid data
• Add support for stations filtering via bbox and name
• Add support for units in distance filtering
• Rename station_name to name
• Rename filter methods to .filter_by_station_id and .filter_by_name, use same convention for bbox, filter_by_rank
  (previously nearby_number), filter_by_distance (nearby_distance)
• Mosmix: Use cached stations to improve performance
