Motivation

There's an error when the direction is 0 as float.
Closes #1050

Summary of changes

• Handle float pattern-match for normalize function

How to test it?

It's hard to trigger, but you can see in the issue how the function was called. If you do Arena.Utils.normalize(%{x: 0.0, y: 0.0}) you get the error.
