Using more than 32 variables in sig_groebner_basis

[sumiya11]

Thank you for implementing sig_groebner_basis.
It would be useful for me to use this function for systems with many variables.
At the moment, I get the following error:

ERROR: LoadError: At most 32 variables currently supported.

@RafaelDavidMohr will have a look in the next weeks.

Adressed in #93.

Thank you! I can confirm that the latest version works with more than 32 unknowns.
