Generate relative parents when writing with baseIRI.

[ajuvercr]

When supplying a baseIRI, the Writer might want follow the same algorithm as path.relative to also allow for relative parent IRIs.

  const baseIRI = "https://example.com/ns/1/2/3/";
  const parser = new Parser({ baseIRI });

  const input = "<a> <../../b> <../..>.";
  const turtle = parser.parse(input);

  const writer = new Writer({ baseIRI });

  writer.addQuads(turtle);
  const txt = await new Promise((res) => writer.end((_, e) => res(e)));
  console.log("Expected\n" + input);
  console.log("Got\n" + txt);

Expected
<a> <../../b> <../..>.
Got
<a> <https://example.com/ns/1/b> <https://example.com/ns/1/>.

Is this feature on the roadmap or should I stick with regexing the resulting output?

There are no plans to implement this at present, but I think a PR that adds this as an opt-in feature would be accepted - so long as there are no associated performance degradations.
