The idea of an owner came from radicle-link storing the signer in the
storage which was needed for performing signing when writing
particular rad references. The peer_id and personal identity was also
stored within the monorepo config.
Since git-storage is just general reading & writing of references and
objects, these concepts are not necessarily needed at this
level. Remove the owner from Write and remove the config module.

When an object does not exist the `find_*` functions will return
None. It will be a common case that users of the API will follow the
pattern of `find_blob(store, oid)?.ok_or(Error::NotFound)`.
Add fallible functions corresponding to each `find_` function
returning a `git2::Error` if the object is not found.

The Updated values only tell the updated value of the target. It can
be useful to also return the previous value, e.g. for reporting,
hooks, etc.
Add `Option<Oid>` to the Update::Direct and Update::Symbolic variants.
