I need a way to convert a message from an Incoming LEEF payload to outgoing CEF format. When I have tried to use parse_leef; and use to_cef(); I appear to get the right format but my payload contains the following format:

Apr 29 06:55:03 x.x.x.x LEEF:1.0|CEF|....

Obviously I need the LEEF field removed and the CEF field in its place. The parse at the other end doesn't know what do to with this formatting.
