Select a key exchange group to use, from the list of groups sent by the peer. In TLS 1.3 handshakes the peer might have provided cryptographic material for a subset of its available groups. Choosing a group for which no share was provided will result in an additional round trip. If none are acceptable, return Group_Params::NONE.
By default this will try to optimize for less round trips even if this results in the usage of a less preferred group.

If this function returns false, unknown PSK identifiers will be rejected with an unknown_psk_identifier alert as soon as the non-existence is identified. Otherwise, a false identifier value will be used and the protocol allowed to proceed, causing the handshake to eventually fail without revealing that the username does not exist on this system.
