Going to be used by Net::SSLhello for TLSv1.3 and support of arbitrary extensions defined here.
Added some definition hashes for decoding and tracing values of these extensions, too:
TLS_EC_POINT_FORMATS, TLS_MAX_FRAGMENT_LENGTH, TLS_NAME_TYPE,
TLS_PROTOCOL_VERSION, TLS_PSK_KEY_EXCHANGE_MODE, TLS_SIGNATURE_SCHEME,
TLS_SUPPORTED_GROUPS
