Construct an iterator.

1) Default constructor. Value-initializes the underlying iterators, and initializes the pointer to parent ranges::join_view with nullptr.
2) Initializes the underlying outer_ iterator with std::move(outer), and the pointer to parent parent_ with std::addressof(parent); then calls satisfy().
3) Conversion from /*iterator*/<false> to /*iterator*/<true>. Move constructs the underlying iterators outer_ with std::move(i.outer_), inner_ with std::move(i.inner_), and underlying pointer to parent parent_ with i.parent_.

[edit] Parameters

parent - a (possibly const-qualified) ranges::join_view
outer - an iterator into (possibly const-qualified) ranges::iterator_t<Base>
i - an /*iterator*/<false>
