TLS 1.3 support #64
Description
While OpenSSL 3 is now supported, there is no mechanism provided for setting which ciphers to use for TLS 1.3. OpenSSL sets these separately (via SSL_CTX_set_ciphersuites()) than for TLS 1.2 and lower (SSL_CTX_set_cipher_list()). See https://www.openssl.org/docs/manmaster/man3/SSL_CTX_set_ciphersuites.html
Most applications I've encountered introduced a new keyword for TLS 1.3 ciphers, but at least one just has you include them in the existing keyword, and it separates them itself. Either is viable.
