constexpr auto begin();
(1) (since C++20)
constexpr auto begin() const
  requires ranges::forward_range<V> && ranges::forward_range<const V>;
(2) (since C++20)

Returns an outer_iterator to the first element of the lazy_split_view.

Let base_ be the underlying view.

1) Equivalent to
constexpr auto begin() {
  if constexpr (ranges::forward_range<V>)
    return /*outer_iterator*/</*simple_view*/<V>>{*this, ranges::begin(base_)};
  else {
    current_ = ranges::begin(base_);
    return /*outer_iterator*/<false>{*this};
  }
}
2) Equivalent to return /*outer_iterator*/<true>{*this, ranges::begin(base_)};.
