Fixes #496 and improves memory consumption on render of game_controls (#501)

Browse Source 
* Fixes #496 using ebiten.SubImage to Render Section of a Surface.

I had to add matching functions to both animation and sprite to get it to be called
for a sprite object.

* Fixed linter warning on comments for Sprite and Animation.

* Removing what's remaining of the old Sprite re-generation and caching.
