BREAKING(io): remove readStringDelim()

[iuioiua]

What's changed

readStringDelim() has been removed from @std/io.

Motivation

This change was made to help push users towards using the Streams API and @std/streams, and make design decisions about which APIs easier.

Migration guide

To migrate, pipe the readable stream through a new TextDelimiterStream instead.

- import { readStringDelim } from "@std/io/read-string-delim";
+ import { TextDelimiterStream } from "@std/streams/text-delimiter-stream";

  using file = await Deno.open("README.md");

  for await (
-   const line of readStringDelim(file, "\n")
+   const line of file.readable
+     .pipeThrough(new TextDecoderStream())
+     .pipeThrough(new TextDelimiterStream("\n"))
  ) {
    console.log(line);
  }
