Generate a keypair.
This is a duplicate crypto_box_keypair, but
is included for api consistency.

Generate a keypair with a given seed.
This is functionally the same as crypto_box_seed_keypair, however
it uses the blake2b hash primitive instead of sha512.
It is included mainly for api consistency when using crypto_kx.
