Review Comment:
I know this seems arbitrary (and probably is), but without this param the
decompressor fails with error:
```
zstd.ZstdError: zstd decompress error: Frame requires too much memory for
decoding
```
I thought about using `DEFAULT_READ_BUFFER_SIZE` but it seems too low for
this param. I can either create a constant or a new parameter if necessary, let
me know.
