startRTSPCamera is returned.

Two fixes were involved, firstly, access unit delimeters were used to denote access units and the Write timeout on rtmpSender's ringBuffer was
increased to stop the 'unable to dump old write' errors. Also made some small changes elsewhere that should fix future issues, particular with
MTS output.

called fuzz.go has been created, which houses the actual fuzz test function. An initial corpus has been added with 3 inputs.
