hex-to-rgb.js

/*
Create a method `convert` that converts a hexadecimal color string into a RGB array.

A hexadecimal color string is a triplet of hexadecimal values (red, blue, green) that begins with a '#'. E.g: #FFD700 will be the gold color : FF for red, D7 for blue, 00 for green.

A hexadecimal digit (base 16) goes from 0 to 9 and then from A to F (10 to 15). Each color group contains two digits, and goes from 00 to FF (255).

A RBG array contains the value of each color group in decimal.

If you convert "#FFD700" into a RGB array, you'll obtain [255, 215, 0].

If the argument is null, empty, not a string, doesn't begins with a '#' or contains an illegal character, throw an Error with the message "Illegal argument".

You MUST use parseInt this time!
