Replace segments
iterator replace( iterator from, iterator to, pct_string_view s);
This function replaces a range of segments with one segment. Reserved characters in the string are automatically escaped. Escapes in the string are preserved.
All iterators that are equal to `from` or come after are invalidated.
Linear in `s.size() + this->url().encoded_resouce().size()`.
Strong guarantee. Calls to allocate may throw. Exceptions thrown on invalid input.
