Add coupling options to JULES namelists

Here I'm looking at which bits of the JULES namelist need to be changed to go from GA7 (u-ah389) to GC3.1 (u-ah981)

• ->um
  • ->namelist
    • ->JULES Science Settings
      • ->JULES radiation options
        • ->l_albedo_obs: true -> false
      • ->JULES sea and sea-ice options
        • ->l_cice_alb: false -> true
        • ->l_saldep_freeze: false -> true
        • ->l_sice_meltponds: false -> true
        • ->l_sice_meltponds_cice: false -> true
        • ->l_sice_multilayers: false -> true
        • ->l_sice_scattering: false -> true
        • ->l_ssice_albedo: false -> true
        • ->l_tstar_sice_new: true -> false
        • ->nice: 1 -> 5
        • ->nice_use: 1 -> 5
        • ->dt_snow_cice: 0.0 -> 1.0
        • ->kappai_snow: 0.50 -> 0.255
        • ->pen_rad_frac_cice: 0.2 -> 0.4
