Support ECSV format

[hombit]

** Feature request**

It would be great if hipscat-import could infer data types from ECSV catalogs, like Gaia DR3. Currently, user is required to provide an empty parquet file with a schema for this catalog.

astropy could help with this task. While its ECSV parser looks very slow, we still could use it just for data type inference:

from astropy.io import ascii

empty_astropy_table = ascii.read(gaia_file, format='ecsv', data_end=1)
empty_astropy_table.write('schema.parquet')
