Pagination Placeholders

[ch4ika]

First, a few things...

• [ ] Is your feature request related to a problem?
• [ ] Will this feature just help you or is it something everyone needs?
• [ ] Have you tried to implement or draft this feature?
• [ ] Is your feature a breaking change?

😄 Describe the solution you'd like

🧠 Describe alternatives you've considered

The possibility if I have something like this:

config.layout("YYYYYYYYY", "XXXXXXXXX", "XOXOXOXOX", "XOXOXOXOX", "XXXXXXXXX", "YYYYYYYYY");

That if O no longer has a PaginationItem, I can also put a placeholder there. Otherwise it will always be filled with air.
