Version comparison and sorting

Not sure if this would be out of scope, but version comparison & sorting could be nice if it was integrated here.

We've been using version_compare for our POC but maybe RPM has different semantics?

See Package::evr() and the EVR struct:

rpmrepo_metadata/src/common.rs

Line 25 in dcb93be

pub struct EVR {

Version comparison and sorting should already be possible. Let me know if there's anything you need that's missing

Nice! Thank you, I'll try it out.
