Add gix blame -L start,end

[cruessler]

This enables running blame for a portion of a file. This feature will be helful for debugging gix blame, in particular in the context of #1743.

Thanks a lot for making blame even better!

Besides my comments which are more like nits to let it appear less rushed, one change I really have to ask for: Changes to gix-blame need to go into their own commit, and be prefixed with feat!: to indicate a breaking change. A single test there probably would be a good idea (or necessity) as well.

The changes to the other two crates can be bundled as they logically are one (core + gitoxide).

Thanks a lot!

Sure, no worries, and thank for letting me know! I’m not fully familiar with all the conventions yet, so always grateful to learn them. :-)

Thanks a lot for the fixes!

Additionally, I have modified the second commits subject to not contain a ! as it's not a breaking change, just a new feature.
