Change Request: frameCount

[tonytoms]

Hi. Thanks a lot for the awesome lib. I was using it in my react app with the SpriteAnimator component. I finding a naming convention bit weird. The 'framecount' is actually not the total frames that will be played from the 'startFrame'. It's actually the ending frame. That is , startFrame=2 ,framecount=5 => will make the lib play frames 2,3 and 4. It's a bit confusing. So, it's a humble suggestion to rename framecount to endframe.
