Resonance reconstruction for LRF=7 does not consider IFG=1

[whaeck]

While looking at the coding in samm.f90, I noticed that the IFG flag (which defines whether or not the widths need to be interpreted as reduced widths or not) is never checked. A simple test has shown that the flag is never checked so evaluations with reduced widths will be treated as if the widths in the resonance parameters are normal widths. As far as I know, no evaluations use reduced widths (but still, the day some evaluation does, we are in trouble).
