Title: Fix set-pixel and get-pixel functions

I think that adding support of ```pixels[]``` to ClojureScript version don't have a sense.
Because user must pack\unpack color to ```pixels[]```:

https://github.com/processing-js/processing-js/blob/master/processing.js#L19153
https://github.com/processing-js/processing-js/blob/master/processing.js#L19136

So, in this case I think that users will use ```set-pixel``` and ```get-pixel``` for working with ```pixels[]```.
Because realization of ```pixels[]``` in Java and JavaScript Processing is different.

P.S. Tests for ```set-pixel``` and ```get-pixel``` maked manual. Because if we run it in common canvas this is raise Security exception (canvas context dirtied by previously loaded images).
