Update `check_values()` to check values other than `NaN` and `Inf`

Because the verification function check_values() may be used multiple times the check the requirement of values in a given array, it shall be updated and generalized to check for values other than NaN and inf.

Other values to check in the current context of Minterpy are non-negativeness (>=0) and positiveness. The check is used mainly in the construction and modification of MultiIndexSet instances. In this particular use case, the arrays must be checked for non-negativeness.
