Using HAVING instead of WHERE filter constraints

[hackel]

It seems that currently this package doesn't allow for filters to add a HAVING constraint instead of WHERE other than using a callback. (Correct me if I'm wrong.) Would it be useful to add this functionality to the package or is it too niche? I'm thinking something like this:

AllowedFilter::partial('my_selected_column')->useHaving(),
// or perhaps
AllowedFilter::havingPartial('my_selected_column'),
// equivalent to: $query->having('my_selected_column', 'like', "%{$value}%"),

I haven't looked into how difficult this would be to implement, just throwing it out there as I currently have the need for it in one of my queries and was surprised it didn't already exist. Thoughts?
