Writing to Parquet fails for extension types that contain lists

[sydduckworth]

If you create an extension type that wraps any kind of list type, conversion to Parquet format fails.
As far as I can tell, this could be fixed by updating the nested_array_to_page function in io/parquet/write/mod.rs to use:

match array.data_type().to_logical_type() {

instead of

match array.data_type() {

I'm happy to do this. Can you assign this issue to me?
