[feature] : Bound aspect ratio between 0 and 1

[MaxGamill-Sheffield]

Is your feature request related to a problem?

Aspect ratio currently bounded between 1 -> inf, which feels like it holds less meaning than 0 -> 1.

Describe the solution you would like.

Change grainstats code:

# Enforce >= 1 aspect ratio
if aspect_ratio < 1.0:
    aspect_ratio = 1 / aspect_ratio

to

# Enforce <= 1 aspect ratio
if aspect_ratio > 1.0:
    aspect_ratio = 1 / aspect_ratio

Describe the alternatives you have considered.
