Misc parameters

• force_asynchronous_dedispersion (boolean, default=false).

  Forces RFI removal and dedispersion to run in separate threads (shouldn’t need to specify this explicitly, except for debugging).

• track_global_trigger_max (boolean, default=false).

  If track_global_trigger_max=true, then the L1 server will keep track of the FRB with the highest signal-to-noise in each beam. When the L1 server exits, it prints the signal-to-noise, arrival time and DM to the terminal.

  This was implemented for early debugging, and is a little superfluous now that L1b is integrated!
