TypeError: Cannot set property 'huffmanTableDC' of undefined at constructor.parse

[anmutech]

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

To reproduce:

// jpeg-js@0.4.3
// TypeError: Cannot set property 'huffmanTableDC' of undefined at constructor.parse
// @ node_modules/jpeg-js/lib/decoder.js:798:40
const jpeg = require("jpeg-js");
const buf = new Buffer("ffd8ffffffc0d8e00080d8000600ffffffdad8ff7fefaad8", "hex");
jpeg.decode(buf);

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