Implement ECDH-ES

[lawliet89]

Probably not the AES**KW variants because ring does not seem to support AESKW.

is still in the works?

There is some mention of ECDH-ES in the source https://github.com/lawliet89/biscuit/blob/e578b4071fb7315dbe9d84d05b2d81672887151e/src/jwa.rs#L418 , what's currently missing?

Support from the Crypto library (ring) is missing. I haven't had the time to implement it with Openssl instead.

There are two PRs for ring to implement https://github.com/briansmith/ring/issues/331, which would allow this to be implemented using ring, I believe.

Thanks @briansmith for letting me know. I'll keep a lookout.
