This PR is finally adding support for integers of arbitrary precision, addressing #13.
It uses the fairly basic implementation by https://sercantutar.github.io/infint/

Introduce new macros:
It also adds the VMBigInteger class. The InfInt.h implementation is slightly adapted for SOM++, but not optimized for performance.
This PR also does not ensure that values fitting into small ints are actually small ints.
