hsla: Just store floats

We are using floats for rgb, and we don't need more precision
for hsl colors either. We use hsl for computing color expressions
like shade(), lighter() and darker(), which are not precisely
specified anyway.

This commit updates the one test where the output changes a
tiny bit due to this.
