Right now, we only allow setting a singular limit for a component that clamps scores and then an implicit clamp at 0.

We either have a positive or negative clamp and gives us the following two ranges of values:

• [0, positive_value]
• [negative_value, 0]

We should allow that we can set both the min and max clamps, defaulting to 0 for both min and max values.

Not sure we would want to apply this for test grading or checkpoints. Thoughts @bmcutler?
