@isomorphic-pgp/sign-and-verify

Currently it has some significant limitations that may make it unsuitable for many projects!

1. It does not check if a key has been revoked. The verify function will still return true if using a revoked key.
2. It only uses the Primary Key (the very first key in an OpenPGP message) and ignores the rest. The verify function will return false if the signature was made by a subkey and not the primary key.
3. It can only deal with RSA key types.
4. It can only deal with detached binary signatures (signature type 0x00)
5. It can't create signatures using private keys that are passphrase protected.

I will happily accept PRs to address these limitations as long as they respect the "keep the bundle size small" project goal.
