Report on compression in describe output #75

Closed tschaub closed 1 year ago

tschaub commented 1 year ago

This adds information about the column compression in the describe output. For the --format json output, compression detail is provided on nested fields. For the non-JSON output, only the top level fields are described. And the compression is only reported based on columns in the first row group.

This also fixes an issue where Parquet to GeoParquet compression changes would only work when the input data was uncompressed.

Fixes #46. Fixes #47.
