[gopherbot]

by johnkgallagher:

All the other compress/* packages include both decompression and compression.
compress/bzip2 only supports decompression.

bonus points if it leverages parallelization.

I now have some time to do this work. There are a few questions I want to ask:

1. Is there still interest in adding compression encoding now?
2. What can I do for you? How to do it? I know that @dsnet has written an encoding code: https://github.com/dsnet/compress/tree/master/bzip2.
   (My issue is closed. The detailed description is here: bzip2：Add bzip2 encoding implementation #40420)

Some blockers getting my bzip2 implementation merged into the standard library is the need for code reviewers familiar with BWT, and also my own time to push the code along through code review. At the moment, I don't have the available bandwidth to commit to an endeavor like this.

Well, it seems that this work cannot be completed in a short time. I will continue to focus on the improvement of the compression library. If you need it, remember to call me. I like compression. Thank you for your reply.
