Multiple transform keyframe animations not working anymore about gltf2usd

@kcoley I created a quick example, 3 bouncing cubes on a surface. Both sets of files from different releases of gltf2usd.py.
cubeBounceFiles.zip

@kcoley I was just having a quick look at your gltf2usd.py master... in relation to this issue. I checked the usda file and it only seems to be building the first animation sequence for 1 cube out of 3 being animated.

In your script gltf2usd.py at line 440. You've have the following in

def _convert_animation_to_usd
animations = self.gltf_loader.get_animations()
 if len(animations) > 0:
            # only use first animation for now
            animation = animations[0]

From what I can determine from the comment and setting animation = animations[0] you're only looping over the first animation.... and you need a for loop to catch multiple keyframes.

Is that right?

@wave-electron yeah that is right. I'll push a fix for this

@wave-electron thanks, a sample model would be great
