QPagination ellipsis slot

Is your feature request related to a problem? Please describe.
no

Describe the solution you'd like
Add an ellipsis slot to modify its default behaviour e.g. to show QPopupEdit to set page number instead of just go directy to next page.

Describe alternatives you've considered
The 'input' pagination variant works but excludes the page buttons and somehow it's not very intuitive nor pleasant to use (according to my collegues and me as well)

Any workaround to override default ellipsis btn behavior?
