A family of functions for reading (Geo)Parquet metadata directly from the file footer; no data pages are read.
Each returns a classed list with format() and print() methods:
gpq_file_info(): file-level summary (sizes, versions, row groups).gpq_schema_info(): the Parquet schema (leaf columns, struct nodes, logical types).gpq_row_groups(): row group and column chunk statistics, with decoded min/max values.gpq_geo_metadata(): the GeoParquet (geo) and GDAL (gdal:*) key-value metadata.gpq_inspect(): all of the above, assembled into one object.
The footer is read with nanoparquet::read_parquet_metadata() and embedded JSON metadata is parsed with
yyjsonr::read_json_str().
