Fix pt frl

This pull request uses the most optimal pt::frl parameters found so far. It also patches the routing bug of FEROL streams: in case that there is only one active FEROL stream, all streams are routed to one port on the RU instead of alternating. It seems there are 2 parameters used for defining the number of streams in daq2Configurator: self.streams_per_ferol and frl.nstreams. Only the latter is set correctly. I fixed it the most straightforward way for the production settings, but this should be reviewed for all cases.
