Missing attribute table from geoparquet files and failing to read them directly in leafmap

[sahandv]

The attribute table from geoparquet files is missing and it's failing to read them directly in leafmap.

leafmap.read_parquet() fails because it expects some sort of detailed attribute table. leafmap.add.vector() fails too, same reason.

The workaround has been to use gdf = gpd.read_parquet() and then leafmap.add_gdf(),

To fix this and potential future problems, we should experiment with different compressions and write_table arguments, as noted in:
