Process Stream Char by Char

Improve the user experience "the ChatGPT way" by incrementally displaying data as it is streamed in.

This utility exposes two methods:

1. stringToReadableStream: Transform a string to ReadableStream type.

   Usage: Convert a string to ReadableStream instance.

   import { stringToReadableStream } from 'process-stream-char-by-char'
   // ...
   const inputStream = stringToReadableStream(inputString)

2. processStreamCharbyChar: If given an input stream of type ReadableStream and a callback function, the method decodes the string and calls the callback function for each decoded character. The decoded character will be passed as an argument to the callback

   Usage: Progressively add data to your react state as it is streamed in.

   import { processStreamCharbyChar } from 'process-stream-char-by-char'
    //...
    processStreamCharbyChar(inputStream, (char) => setState((prev) => prev + char))
