Replace segments
templateiterator replace( iterator from, iterator to, FwdIt first, FwdIt last);
This function replaces a range of segments with annother range of segments. Reserved characters in the new range are automatically escaped.
All iterators that are equal to `from` or come after are invalidated.
None of the character buffers referenced by the new range may overlap the character buffer of the underlying url, or else the behavior is undefined.
Linear in `std::distance( first, last ) + this->url().encoded_resouce().size()`.
Strong guarantee. Calls to allocate may throw.
