> I am using the default macOS build of R arrow 1.0.1 (R 4.0.2) and it doesn't support zstandard/zstd for compression:
> {code:r}
> > arrow::write_parquet(cars, '~/Downloads/cars.parquet', compression = 'zstd')
> Error in parquet___arrow___FileWriter__WriteTable(self, table, chunk_size) : 
>   NotImplemented: ZSTD codec support not built
> > arrow::codec_is_available('zstd')
> [1] FALSE
> {code}
> Like ARROW-6960 which adds the lz4/zstd support in Windows, It'd be a great to have the zstd support by default in macOS as well.
> I don't know if I have the right knowledge to add such support, but let me know how I can help. Thank you for making this great package!
