dsa: Add initial DSA implementation (#471)
Adds an initial implementation of DSA (see #8) The following things work when tested against OpenSSL: - The generated keys are valid and can be imported and exported from/to their DER/PEM representation - Signatures generated by this library can be successfully verified - Signatures can be imported and exported from/into their DER representation - Signatures generated by OpenSSL can be successfully imported and verified
