Move to Python API for HYDRA exceedance frequencies

[veenstrajelmer]

Currently manually extracting HYDRA data:

• currently manually extracting exceedance frequencies from Hydra-NL: Hydra-NL manual exceedance frequency extraction #107. However, the current Hydra-NL freqs are significantly different than the ones used before (csv) and further away from the measurements, why? The latter is mainly relevant for HOEKVHLD, so this might also just be an exception.
• databases WBI2017 (zichtjaar 2023) are available online via STACK
• avoid need for manual extraction and p-drive link for HYDRA-NL data by moving to HYDRA-RING Python API
• HYDRA-RING is executable, so this can be called by using database as input, but requires sqlite database (which requires quite some work to set up properly). In 2024 there will be worked on a HYDRA-RING Python API/wrapper, which makes this easier (https://issuetracker.deltares.nl/browse/HRING-2043)
• prevent the need to supply dict with 'Hydra-NL' distribution, this is typo-risky

Wishlist for HYDRA-RING Python API:

• retrieve results based on user-defined xy-coordinates, API gets values nearest locationid from correct database automatically (including a max_distance parameter)
• retrieve results for a user-defined list of frequencies
• retrieve values relevant for kw 2011/2021/etc. This depends on "zichtjaar" 2011(?)/2023/2035/etc and SLR choices
• include model uncertainty (or not)
• pip installable with light dependencies (single package that does not require separate artifacts)
• no need to manually download databases from somewhere
• single line/request to retrieve list of exceedance frequency values for a particular station
