A trait to determine the lowest layer type of a stack of stream layers.
Defined in header <boost/beast/core/stream_traits.hpp>
template< class T> using lowest_layer_type = see-below;
If t.next_layer()
is well-defined for an object t
of type T, then lowest_layer_type<T> will
be an alias for lowest_layer_type<decltype(t.next_layer())>,
otherwise it will be the type std::remove_reference<T>.
