Uphill character sprite tests

First attempt to adapt my flat ground sprite to running uphill.

Referenced a snippet from this Redbull video for rough key frames.

The initial tests in the game world though, don't look so great. Looks like
she's pushing too much for the gradient that she running on. Might be
because my reference was quite a steep race and they were pushing at a
steeper incline.
