[Python] Expose Parquet ZSTD compression

    Details

      Description

      It seems like in the python/pyarrow/_parquet.pyx file there's a check for the supported compression scheme:

      cdef int check_compression_name(name) except -1:
          if name.upper() not in ['NONE', 'SNAPPY', 'GZIP', 'LZO', 'BROTLI', 'LZ4']:
              raise ArrowException("Unsupported compression: " + name)
          return 0

      which does not include ZSTD (Zstandard).  From my understanding it should be supported in the underlying c++ library already.  Is it possible to add that support?
