Allow disabling hilbstd because of int overflow errors

[ren]

I repeatedly get the following error in many of my computations:

product criterion:252832 chain criterion:42988
   ? int overflow in hilb 1
   ? error occurred in or before primdec.lib::radicalReduction line 6854: @hilb = hilb(I, 1, @w);`
   ? leaving primdec.lib::radicalReduction
   skipping text from `;` error at token `)`
   ? leaving primdec.lib::radicalSLIteration
   ? leaving primdec.lib::radicalSL
   ? leaving primdec.lib::radical

The ideals that I am handling are quite manageable otherwise, for example Groebner bases are computed within seconds (see attached file).

Hence: can we please introduce a global option which disables hilbstd?

now (39a48d0ca8c0ddf16730a974efdccf3a0b8009a2) hilbstd for primdec.lib is done in groebner. If you want to avoid hilbstd, substitute groebner by for example std by adding the following line to your LIB/.singularrc

groebner="parameter def i;return(std(i));";
