Review Comment:
Do we need this handling? Could we just interpret string 'none' value to
mean something different from not setting the write.parquet.compression-codec
property at all?
I think it would be simpler to just propagate the string value directly to
the compression option of the
[ParquetWriter](https://arrow.apache.org/docs/python/generated/pyarrow.parquet.ParquetWriter.html):
"compression[str](https://docs.python.org/3/library/stdtypes.html#str) or
[dict](https://docs.python.org/3/library/stdtypes.html#dict), default ‘snappy’
Specify the compression codec, either on a general basis or per-column.
Valid values: {‘NONE’, ‘SNAPPY’, ‘GZIP’, ‘BROTLI’, ‘LZ4’, ‘ZSTD’}."
