The crypto types are useful to use in other components that are
separate from the radicle crate, e.g. the incoming radicle-cobs
crate.
Separate out the types into a radicle-crypto crate. This crate defines
the usual PublicKey, SecretKey, and Signature types. It also provides
the ssh functionality, under the `ssh` feature. It is also necessary
to provide the `From` impl for `Component` here, which again is
guarded by the `git-ref-format` feature.
The `Arbitrary` implementation are moved. The arbitrary decision of
redefining `ByteArray` in both radicle-crypto and radicle was made.
