set scm_iop_lhflxshflxTg = T for BOMEX & DYCOMSII-RF01 SCAM cases

scm_iop_lhflxshflxTg = F for all scam cases, meaning lhflx,shflx & Tg are not read in from the IOP file, but computed by the surface components. Some IOP's have protocols where they need to be read in from the IOP file, typically a fixed surface flux with time. Two such cases are BOMEX & DYCOMSII-RF01, and so scm_iop_lhflxshflxTg needs to be set to .true. for these cases.

There may be other IOP cases in the usermods directory that also need to follow the protocol. I will add them to this issue as I become aware.
