The main dependant of `radicle-git`, and its crates, is [`heartwood`].
It is licensed under MIT or Apache-2.0, which has been incompatible with the GPL-3.0 license.
Since the intellectual property of this code base is with the Better Internet Foundation, it was
decided to re-license code in this repository to make the upstream repository compatible.
- Remove the license headers (and instructions to add them)
- Add MIT and Apache-2.0 licenses
- Remove the GPL-3.0 license
- Change the license declarations in the `Cargo.toml` files

To help with clarity and potential publishing of the crates, the full
`radicle-` prefix is used for the crate names.
Note that it wasn't chosen got `git-ref-format` and `git-trailers`
since they are truly general libraries (bar the feature flag for link
specific reference names).
