Text reader doesn't accept byte arrays of text anymore

[mtcalvin]

I'm unsure if this is a regression or if it was never intended behavior in the first place.

Previously, passing text data as a byte array to makeReader would still return a functioning text reader. Now it throws an error:

var ionJs = require("ion-js")
var input = "{foo:bar}";
var arr = new Uint8Array(input.length)
// A more realistic example would be loading a text file from disk as a Buffer (node.js) or Blob (HTML5)
for (var i = 0; i < input.length; i++) arr[i] = input.charCodeAt(i)

var reader = ionJs.makeReader(arr);
console.log(reader.next().name);

TypeError: this._src.charCodeAt is not a function
