[Feature Request] Add support for cursor pagination

[halaei]

Is your feature request related to a problem?

This feature was added to Laravel 8. Please see the docs: https://laravel.com/docs/8.x/pagination#cursor-pagination.

Describe the solution you'd like

Currently it doesn't work on this package. The first reason is that in this package orders are stored differently in builder objects and therefore Query|Eloquent\Builder::ensureOrderForCursorPagination() methods doesn't return the expected results. So the fix can be to override ensureOrderForCursorPagination() in this package or make sure orders arrays in mongodb builder objects are the same format as those in the original Laravel ones.
