Add Corsica station

The station has data from at least 2019 and at least until 2024. The station was discarded from the IEA Task 16 benchmark due to poor data quality.

Using Google Maps Street View, the coordinates can be identified as: 41.91226, 8.65312

The elevation from Google Earth is 78 (of the building roof).

The station is on the campus of the University of Corsica Pasquale Paoli.

No file or test is named in the issue. Start by inspecting existing station records and the repository’s station-data entry point to find the required schema and validation; add the Corsica station with the supplied coordinates, elevation, campus context, and 2019–2024 data range, then run the project’s available checks.
