A suggestion to enable styling the sticky and the non-sticky headers differently. Currently, the background can be specified for the sticky ones but there might be cases when more than the background (eg. foreground, font style, etc) needs to be different as well. The perfect solution would be to modify groupSeparatorBuilder() to include the sticky parameter but that would be a breaking change. So, I added a new builder callback. If you consider this approach acceptable, you might want to deprecate the orginal one some time in the future.
