codes to tell libcurl how to act:
.IP CURLKHSTAT_FINE_REPLACE
The new host+key is accepted and libcurl will replace the old host+key into
the known_hosts file before continuing with the connection. This will also
add the new host+key combo to the known_host pool kept in memory if it wasn't
already present there. The adding of data to the file is done by completely
replacing the file with a new copy, so the permissions of the file must allow
this. (Added in 7.73.0)
.IP CURLKHSTAT_FINE_ADD_TO_FILE
The host+key is accepted and libcurl will append it to the known_hosts file
before continuing with the connection. This will also add the host+key combo
