onefetch uses gitoxide

[Byron]

• traverse commits
• mailmap support #366
• index for size computation
• traverse tags, references
• a flag to turn support for shallow history support off - by default we just stop iteration if a commit can't be found, but people can turn it on to see errors (like now) if a commit can't be found.
• git-odb support for git-replace with override in handle
• git-repository support for git-replace
• config 'user.name', remote information
• split index support
• peel tag
• git status/pending changes (see Replace libgit2 with gitoxide o2sh/onefetch#628 for details)
