Prevent trailing spaces in uhslc catalog

[veenstrajelmer]

Follow-up from #1185. UHSLC-fast also has ['Rangiroa Atoll ', 'Tubuaï '] stations with trailing spaces:

import dfm_tools as dfmt
ssc_catalog_gpd = dfmt.ssh_catalog_subset(source="uhslc-fast")
name_endwithspace = ssc_catalog_gpd["station_name"].loc[ssc_catalog_gpd["station_name"].str.endswith(" ")]
print(name_endwithspace.tolist())

Requested on 8-5-2025 to fix this at the source. If this is not feasible/needed, trim them in dfm_tools.
