fix: use transform translate for nipple front

[MCArth]

As discussed in https://github.com/yoannmoinet/nipplejs/issues/168, this uses transform: translate instead of setting top/left on the nipple front.

Two notes that might be worth their own issue:

The npm prepare script runs on npm install, and setting NODE_ENV fails on windows. I'd personally prefer cross-env for something like this. Also, 6 of the tests fail without any of my changes? 6 still fail with them.

If I read the code correctly, I also think if (opts.follow) { should be if (opts.follow && !opts.dataOnly) { here

Any chance we could revive this PR and make it happen? :) I'm also seeing some significant FPS drop when moving the joystick.

@verekia I've been using this branch in production since I made this PR and it seems stable, you could depend directly on it until @yoannmoinet deals with the pr
