reachedBottomPublisher offset not working as expected.

Appears the UIScrollView.reachedBottomPublisher offset is not working as expected.

Currently the threshold is calculated by using max bracketing on offset of calculating the y to compare using visible height:

let threshold = max(offset, self.contentSize.height - visibleHeight)

However in order for this to work the publisher would have to be setup as:

collectionView
  .reachedBottomPublisher(collectionView.contentSize.height - visibleHeight - offset)
  .sink {

Which I don't believe is correct given when dynamically inserting content the content size will change.

I believe the threshold needs to be calculated considering the offset such as:

let threshold = (self.contentSize.height - visibleHeight) - offset
