CHANGES:

• Bugfix: do not filter signature_algorithms based on server certificate. Since signature_algorithms is also used for client authentication (as SignatureAlgorithms extension in CertificateVerify), previously the client needed the same key type as the server. Discovered in https://github.com/roburio/albatross/commit/df434da0e531e1b0c8091a0fc82e8b37ed319e7a
