Title: Allow access to the original size of frame images

For some texture packers, like stablexui, there is a field storing the original size of the images.
That is usefull, for example when one one wants to center the frames.

Unfortantly I do not know how to load this information for all importers, so this does this only for LibGDX and TexturePacker.
