Panic to clear to the operator something is wrong. Panic'ing like this
is ok in debug mode, but must be avoided in production.

Collaborative object IDs are derived from their commit oid. These
IDs must be reproducible to support testing the client's example. All but
one of the parameters used to derive the Object ID is the commit's Author
and committer timestamp.
Introduce an environment variable 'RAD_COMMIT_TIME' to set both Author and
Committer timestamp when creating a commit in the cob module.
Use single variable, instead of Git's two (for author and committer), to
keep the changes simple. The function being modified returns a single
timestamp which is derived from the author's.

Sometimes it is more efficient to perform multiple operations at once
and store those in the collaborative object graph together.
Change the contents to be a non-empty sequence of byte sequences,
i.e. NonEmpty<Vec<u8>>. These are stored as blobs in a git tree in
order by their index in the non-empty sequence. They are, in turn,
retrieved in order of their original index.
Change the conversion of an `EntryWithClock` to return a non-empty
sequence of `Op`s, which are in turn used to apply many changes in
each `from_history` implementation.

This is a minimal port of the collaborative objects code from
radicle-link[0].
A `CollaborativeObject` is made up of a `History` of `Change`s that
are expected to be stored in a `git` backend.
The library exposes a CRU series of functions `create`, `get`, `list`,
and `update`.
This implementation differs, to previous one, in that it does not
assume any kind of identity system -- its only assumption is that
identities have an identifier and can be addressed in the `git`
database. This means that it does not require an `author` to be passed
in and it only uses the `resource` (previously `authorizing_identity`)
to store its content-address in the `Change`.
It also foregoes any caching to simplify the port and not make any
early optimisation assumptions.
