Add FIFO pre-create to the replay startup script

Add FIFO pre-create to the replay startup script

The replay run script now provides the ability to pre-create
the FIFOs either with an explicit list, or by reading the
input file to suss out the message types it contains.

The run script also provides a way to gate and/or delay
the start of the replay binary in order to allow for better
synchronisation with a FIFO reading process.
