MASTR: load any dated open-mastr dump (date-agnostic paths + glob fn)

[MaykThewessen]

What

Makes the MASTR() loader work with any dated open_mastr dump instead of only the hardcoded bnetza_open_mastr_2025-02-09 release. Fixes parts 2 and 3 of #299.

Why

Today the loader cannot consume a newer MaStR dump even if you point the config at one:

1. The storage-units CSV is read from a hardcoded path that embeds the release date, so a newer dump (different bnetza_open_mastr_<date>/ inner folder) raises KeyError.
2. ThermischeNutzleistung exists in the Zenodo CSV dump but not in the open_mastr bulk export, so a non-Zenodo-shaped dump breaks the CHP-detection assign.

See #299 for the full description.

Changes

• data.py — match bnetza_mastr_storage_units_raw.csv by suffix rather than the hardcoded dated folder prefix.
• data.py — CHP detection falls back to KwkMastrNummer alone when ThermischeNutzleistung is absent.
• utils.py (get_raw_file) — a glob fn selects the newest matching local file (ISO dates sort chronologically); falls back to downloading the URL's basename when nothing local matches. Non-glob fn is unchanged.
• config.yaml — default MASTR.fn to the glob bnetza_open_mastr_*.zip, keeping the frozen Zenodo url as the download seed.

Compatibility

Behavior-preserving on the current Zenodo dump: a fresh checkout has no local match, so get_raw_file falls back to downloading bnetza_open_mastr_2025-02-09.zip, and the suffix match reads the same inner CSV as before. Pin a specific dump by setting fn to a literal filename.

Not included here (deliberately, to keep this focused): the optional helper that rebuilds a current dump from the open_mastr bulk export. Happy to add it in a follow-up if maintainers want in-repo refresh tooling.

Test plan

• import powerplantmatching / module parse
• Maintainer CI (Duke/Java-gated tests)

Closing as a duplicate of #298, which makes the identical date-agnostic changes (storage_units suffix-match, ThermischeNutzleistung guard, glob fn in get_raw_file, config glob) and additionally ships the build helper script. Apologies for the noise: #298 is the one to review.
