GenPrivKey generates a new ECDSA private key on curve secp256k1 private key.

GenPrivKeyFromSecret hashes the secret with SHA2, and uses that 32 byte output to create the private key.

PubKeySize is comprised of 32 bytes for one field element (the x-coordinate), plus one byte for the parity of the y-coordinate.

PrivKey defines a type alias for an ecdsa.PrivateKey that implements Tendermint's PrivateKey interface.
