Keypair should be named KeyPair?

May I submit a pull request changing Keypair to KeyPair?

FWIW the ed25519 crate also uses Keypair.

I would argue "keypair" is commonly used as a closed compound word, and as such the Keypair capitalization is just as valid as KeyPair.

As of #242 it's called SigningKey
