Enable CPLEX v12.7.1

[blegat]

Nothing has changed in cpxconst.h except of course CPX_VERSION and CPX_VERSION_MODIFICATION and adding the parameters:

CPXPARAM_H = 1
CPXPARAM_Sifting_Simplex = 1158
CPXPUBLICPARAMS_H = 1
CPX_PARAM_SIFTSIM = 1158

Did you account for the manual changes in full_defines_1271.jl? What's the diff between full_defines_1271.jl and full_defines_127.jl?

[blegat]

I did the manual changes needed (replace Cint by Cchar and remove Cint for floats). The diff is as follows

1c1
< # This list was obtained through AWK with Cplex 12.7 (and then pared down).
---
> # This list was obtained through AWK with Cplex 12.7.1 (and then pared down).

Looks good, I think the _H constants like CPXPARAM_H and CPXPUBLICPARAMS_H can be excluded since they're just header guards.

There's also #122 if you're feeling generous, but up to you.
