Invoked when a CTCP query is received in a message.
IrcClient.onMessage is not invoked for the given message
when onCtcpQuery has a non-zero number of registered handlers.
Note:
This callback is only invoked when there is a CTCP message at the start
of the message, and any subsequent CTCP messages in the same message are
discarded. To handle multiple CTCP queries in one message, use
IrcClient.onMessage with $(DPREF ctcp, ctcpExtract).
