Transform a stream into a stream where each chunk is divided by a given delimiter.

import { TextDelimiterStream } from "https://deno.land/std@0.224.0/streams/text_delimiter_stream.ts";
const res = await fetch("https://example.com");
const parts = res.body!
  .pipeThrough(new TextDecoderStream())
  .pipeThrough(new TextDelimiterStream("foo"));
