implement drop_* and take_* family of views for C++29 #146
Description
This project is more involved given that there's no paper as of this moment to propose these. However, the first step would be an implmentation. This comes from the c++26 plan for ranges as a Tier 1 suggestion that did not get proposed.
views::drop_last and views::take_last
views::drop_last_while and views::take_last_while
views::drop_exactly and views::take_exactly
