Able to specify size and fps params

[kakakikikeke-fork]

Abst

The opts variable has to have a size and fps values in a getMjpegStream method of bebop.js

How to use

You can use it following as (e.g. in node-bebop/examples/opencv-face-tracking.js )

var drone = bebop.createClient(),
    opts = {'size': '320x240', 'fps': 24, 'quality': 1},
    mjpg = drone.getMjpegStream(opts),
    w = new cv.NamedWindow("Video", 0),
    buf = null;
