A request came in through @malecki that a user wanted to be able to filter
crosstabs()
, here's minimal support. I think probably the filtering information should be included in the output, but I'm not sure if that's required.Note that I have chosen to implement in a way that mirrors the rest of the crunch package, where the filter is pulled from the dataset. This means that behavior could change. I'm happy to ignore the dataset filter if you want that inconsistency.
Also I don't really get the testing strategy, so didn't add tests. I did confirm that filters work as expected manually.
