Initially, radicle-source was envisioned to be another layer on top
of radicle-surf, however, it ended up duplicating a lot of concepts.
We consolidate them by merging radicle-source into radicle-surf.
This meant removing modules branch.rs, tag.rs, oid.rs and error.rs.
The information on how many line insertions and deletions happened in a
diff, as well as files changed is something that is used multiple times
downstream, so it makes the code terser by implementing this
function here.
