InversePowerTimesNumberCommutative

Extractor object for commutative operations between an InversePower and a value that can be powered, represented by CanPower[eager.Number].

This object extends CommutativeExtractor, enabling it to automatically handle both (left, right) and (right, left) orderings in commutative binary operations. Specifically, it extracts:

• An InversePower from the "left" side of the expression, provided the base of the inverse power (n) is greater than 1.
• A CanPower[eager.Number] from the "right" side of the expression.

The unapply method allows pattern matching to operate on pairs of expressions, extracting valid (InversePower, CanPower[eager.Number]) pairs regardless of their position in the tuple.
