Preprocess CSV point data into Josh’s .jshd format.

CSV must have columns named exactly “longitude” and “latitude”. All other columns are available as variables. The timestep parameter is required to specify which simulation timestep the data maps to.

Note: CSV preprocessing uses brute-force nearest-neighbor lookup, which may be slow for large files. For large datasets, consider converting to GeoTIFF first.
