This revamps Filter API to improve support for multiblock dataset and distributed use-cases. Filters now operate on MultiBlock alone thus `Filter::Execute(MultiBlock&)` is the primary method. `Filter::Execute(DataSet*)` is only provided as an convenience that internally puts the dataset into a MultiBlock and calls the primary method. Subclasses can provides PreExecute and PostExecute overrides to handle init/reduction operations for filters with operating on multiple blocks. Since blocks can be distributed, filters are expected to handle that as well. Subclasses can provide `PrepareForExecution(MultiBlock*..)` to customize behavior for handling multiblock inputs. Default is to simply loop over blocks.
