Update ECDSA test vectors

- Update the protobufs following the new template. This includes
  deciding the representation of the public and secret keys. I've
  settled on using the secret value and the uncompressed public point
  since other encodings can easily be derived from them.
- Generate the JSON file that defines the vectors files available
  depending on the parameters.
- Generate CSV tables that indicate whether there are compliance or
  resilience test vectors for a given combination of curve and hash
  function.
- Remove the old vectors/ECDSA.py module.
