The three container adapters should each have a deduction guide allowing the deduction of the value type `T` from the supplied container, potentially constrained to avoid confusion with deduction from a copy/move constructor.

Proposed change: For each container adapter, add a deduction guide of the form

>     template <class Container>
>     adapter(const Container&) -> adapter<typename Container::value_type, Container>;
