Add a `--strict` argument to enable this. `--strict` takes a list of machine types (as reported by STIDP) for which to enable strict mode, for example `--strict 8562,8561,3907,3906,2965,2964` will enable it for models z15 - z13. Alternatively, strict mode can be enabled for all but the listed machine types by prefixing the list with a `!`, for example `--strict !1090,1091,2064,2066,2084,2086,2094,2096,2097,2098,2817,2818,2827,2828` will enable it for z/Architecture models except those older than z13.
