🎨 Adjust tuple concepts - #396
Merged

Conversation
Problem: - Algorithms like `all_of` don't work with `std::tuple` or `std::array`. Solution: - Adjust concepts to separate `has_tuple_protocol` and `has_array_protocol` (note: `has_array_protocol` subsumes `has_tuple_protocol`. - Allow tuple algorithms to work with `std::tuple` by constraining on `has_tuple_protocol` instead of `tuplelike` (which means just `stdx::tuple`). - Add more `unrolled_*` algorithms to deal with those use cases for arrays and spans.
