Matrix 4 video URL generator

/**
 * Matrix 4 video URL generator
 * by: gil0mendes <gil00mendes@gmail.com>
 * 
 * [ALERT]
 * Please keep in mind that this code can stop working due to website changes. I really don't know if they will keep 
 * the files after announcing the trailer or film release.
 * 
 * [CONTEXT]
 * Matrix 4 teaser was announced with a interactive website that allows you to chose between the red and blue pill. It 
 * leads us to a specific video that at the middle says the current hours. It seems like they implemented this by 
 * generating a unique video for each day minute.
 * 
 * [GOAL]
 * After some reverse-engineering I discovered how they generate the URLs for each minute and pill choice. This code, 
 * generates an URL for the given hour and pill choice the user gives to the console.
 * 
 * [USAGE]
 * node index.js <time> <red|blue>
 * example: node index.js 1045 red
