Refactor or replace macm_workflow with MACMWorkflow class #850
Description
I was thinking of refactoring the macm_workflow with CBMAWorkflow and PairwiseCBMAWorkflow.
Another alternative would be creating a new class MACMWorkflow that is fitted to a dataset and mask and uses CBMAWorkflow and PairwiseCBMAWorkflow to perform the meta-analysis correction and diagnostic depending on the estimator.
