TypeError: Cannot read property '0' of undefined at quantizeAndInverse

[anmutech]

I found this error by fuzzing the jpeg-js NPM package.

To reproduce:

// jpeg-js@0.4.3
// TypeError: Cannot read property '0' of undefined at quantizeAndInverse
// @ node_modules/jpeg-js/lib/decoder.js:378:26
const jpeg = require("jpeg-js");
const buf = new Buffer("ffd8ffffffc2d88c2b008400e803ffda8c2b0000ffd8ffd9d8ef00000000b3d8", "hex");
jpeg.decode(buf);

I would be glad to help fix this error unless someone more knowledgable about the JPEG standard can do so.
