Ability to use xdelta in rdiff-like way #185

Hello!

I'm using rdiff and plans to replace it by xdelta because it's very slow.

But I can find ability to generate delta file from "signature" of old file and 
new version of real file.

In other worlds in rdiff:
rdiff --statistics signature old_version_raw_file old_version_raw_file.signature

rdiff delta old_version_raw_file.signature new_version_of_file result.delta

Can I do something like this with xdelta3? I can't compare two files in one 
place because old version on remote server.

Xdelta doesn't work this way, it uses a weak checksum.
