python3-ecdsa: Upgrade 0.15 -> 0.16.0

Upgrade to release 0.16.0:

- Support for reading and writing private keys in PKCS#8 format.
- to_pem and to_der now accept new parameter, format, to specify
  the format of the encoded files, either the dafault, legacy
  "ssleay", or the new pkcs8 to use PKCS#8. Note that only
  unencrypted PKCS#8 files are supported
- Add allow_truncate to verify in VerifyingKey, it defaults to
  True, when specified as False, use of large hashes smaller than
  curves will be disallowed (as it was in 0.14.1 and earlier)
- Correctly calculate signatures for private keys equal to n-1
- Make PointJacobi and thus SigningKey and VerifyingKey pickleable
- to_pem functions return bytes not str, document them as such
- from_pem and from_pem in SigningKey returns SigningKey, document
  them as such
- Ensure that version checks will work with Python 4.
- Format the source with black.
- Fix uses of assert_ in test suite.
- Use newer Ubuntu in Travis to test against OpenSSL 1.1.1 (and
  thus test the interoperability of ECDH code in Travis).
