Suggestion: incorporation with `lrzip`

[Kamila Szewczyk]

I'll let the benchmarks speak for themselves. boost.tar is all Boost versions released after 2016; around 9GB of data.

 9103636480 boost.tar

 1185929228 boost.tar.xz

Seems like bzip3 wins with lzma and bzip2, but we'd have to integrate it into lrzip to see how much it improves matters (regarding timing, etc...)

Having received response from the lrzip maintainer, closing.
lrzip is in the maintenance state and the author is hesitant to add new features.
