Revision parsing

Resolve git revision strings.

rev_parse

Repo.rev_parse(spec: str) -> str / pygitx.rev_parse(repo, spec) -> str

Resolve a revision spec to a hex object id. Accepts typical git syntax:

• HEAD, HEAD~N, HEAD^

• Branch names

• Tags

• Short or full oids

print(repo.rev_parse("HEAD~1"))
print(pygitx.rev_parse(repo, "main"))
