add new F type = 4 model

[k-doering-NOAA]

F type 4 was just added into main, so it would be useful to convert an existing model to use F method 4 in the test set. In theory, I think a model with multiple fleets and some high F values would be a good one to convert (@Rick-Methot-NOAA feel free to provide more guidance on a useful model)

Let's convert vermilion with this setup: 4 # F_Method: 1=Pope; 2=instan. F; 3=hybrid; 4=fleet-specific parm/hybrid (#4 is recommended) 3 # max F or harvest rate, depends on F_Method # for Fmethod 1; no additional F input needed # for Fmethod=2; read overall start F value; overall phase; N detailed inputs to read # for Fmethod=3; read N iterations for tuning for Fmethod 3 # for Fmethod=4; read list of fleets needing parameters; syntax is: fleet, F_starting_value (if start_PH=1), first PH for parms (99 to stay in hybrid) # for Fmethod=4; then read N tuning loops for hybrid fleets 2-3 normally enough #Fleet start_F first_parm_phase 1 0.05 4 2 0.05 4 3 0.1 4 4 0.04 1 -999 1 1 3 #_number of tuning loops for hybrid fleets; 4 good; 3 faster

Ok, if vermillion snapper is the one, I think we should add a second version of the model, since vermillion is our only F method 2 model. Thanks for pasting in the setup!
