IsImaginaryExpressionCommutative

An extractor object that determines if a pair of expressions is related through an imaginary expression in a commutative manner. This means that the imaginary component can appear on either side of the tuple, and the extractor will match in both cases.

The extractor takes a tuple of two Expression objects as input and attempts to find one of the expressions being an IsImaginaryExpression. If a match is found, it extracts the eager value from the IsImaginaryExpression and returns it along with the other expression in the tuple.
