Allow specifying Zstandard compression level
ZstdCompressorOutputStream allows to compress data using Zstandard, but the default compression level of 3 is hard-coded.
Programs that wish to use a different compression level must reimplement ZstdCompressorOutputStream.
I suggest we add a constructor that takes a compression level and passes it to
`new ZstdOutputStream(...)`.
