Abstract methods
Returns a pipe that incrementally decompresses input according to the GZIP format as defined by RFC 1952 at https://www.ietf.org/rfc/rfc1952.txt. Any errors in decompression will be sequenced as exceptions into the output stream. Decompression is handled in a streaming and async fashion without any thread blockage.

The chunk size here is actually really important. Matching the input stream largest chunk size, or roughly 8 KB (whichever is larger) is a good rule of thumb.

- Returns
Returns a pipe that incrementally compresses input into the GZIP format
as defined by RFC 1952 at https://www.ietf.org/rfc/rfc1952.txt. Output is
compatible with the GNU utils gunzip utility, as well as really anything
else that understands GZIP. Note, however, that the GZIP format is not
"stable" in the sense that all compressors will produce identical output
given identical input. Part of the header seeding is arbitrary and chosen by
the compression implementation. For this reason, the exact bytes produced
by this pipe will differ in insignificant ways from the exact bytes produced
by a tool like the GNU utils gzip.

GZIP wraps a deflate stream with file attributes and stream integrity validation. Therefore, GZIP is a good choice for compressing finite, complete, readily-available, continuous or file streams. A simpler deflate stream may be better suited to real-time, intermittent, fragmented, interactive or discontinuous streams where network protocols typically provide stream integrity validation.

- Value Params
- bufferSize
The bounding size of the input buffer. This should roughly match the size of the largest chunk in the input stream. This will also be the chunk size in the output stream. Default size is 32 KB.

- Value Params
- bufferSize
The buffer size which will be used to page data into chunks. This will be the chunk size of the output stream. You should set it to be equal to the size of the largest chunk in the input stream. Setting this to a size which is ''smaller'' than the chunks in the input stream will result in performance degradation of roughly 50-75%. Default size is 32 KB.
