Optimize ZSTDCodec::doUncompress()

Summary:
It is ~10% faster to call `ZSTD_decompress()` than use the
streaming API. The streaming API does some extra `memcpy`s that we
can avoid. We are working on improving the speed of the streaming
API in the case where all the data can be processed in one shot,
but that won't be available in the stable ZSTD api for a few versions.
