bundle: optional multithreaded compression, ATM zstd-only

Compression type can be a huge chunk of "hg bundle", especially when
using the higher compression levels. With level=22 and threads=7, the
NetBSD test repository took 28:39 wall time and 157:47 user time.
Before, level=22 would take 129:20 wall time and 129:07 user time.
