/**
* Reader utility for strings.
*
* @example
* ```ts
* import { StringReader } from "https://deno.land/std@$STD_VERSION/io/string_reader.ts";
*
* const data = new Uint8Array(6);
* const r = new StringReader("abcdef");
* const res0 = await r.read(data);
* const res1 = await r.read(new Uint8Array(6));
*
* // Number of bytes read
* console.log(res0); // 6
* console.log(res1); // null, no byte left to read. EOL
*
* // text
*
* console.log(new TextDecoder().decode(data)); // abcdef
* ```
*
* **Output:**
*
* ```text
* 6
* null
* abcdef
* ```
*
