these are actually void functions

[schochastics]

similar issue as with #15

@chainsawriot do you think this is a viable way for ada_clear_* and ada_set_*? or is there a shortcut?

ada_string ada_clear_port1(ada_url url) noexcept {
  ada::result<ada::url_aggregator>& r = get_instance(url);
  if (!r) {
    return ada_string_create(NULL, 0);
  }
  r->clear_port();
  std::string_view out = r->get_href();
  return ada_string_create(out.data(), out.length());
}

@schochastics There should be a way to do that without rewriting ada_clear_*. Let me try.

[chainsawriot]

std::string Rcpp_clear_port(String s) {
  std::string_view input(s.get_cstring());
  ada_url url = ada_parse(input.data(), input.length());
  ada_clear_port(url);
  std::string res = charsub(ada_get_href(url));
  ada_free(url);
  return res;
}

Not vectorize, but proof of concept.

@chainsawriot I think I get it. Do you mind if I implement this, or do you want to do this yourself?

[chainsawriot]

@schochastics Please do that.
