From: Benjamin Szőke <[email protected]>
Add 7-Zip support in conversion types and commands. Default arguments of 7-Zip
are compression level: 9, method: BZip2, extension: zip. All these are
overridable from local.con for any other use case in user side. First goal was
to make an alternative zip conversion which can operate faster in multi-thread
systems (on many CPU core), normal zip is just a single thread compression.
7-Zip can do a zip compression in multi-thread processing, so it is fine to use
and speed up it.
