Clamp the value between 0 and 1 to avoid tinygradient errors. (#343)

* Clamp the value between 0 and 1 to avoid tinygradient errors.

Previously, we could get a coefficient greater than 1, causing SquadJS to crash. One case is described [here](#342). 
Now we clamp the ratio between 0 and 1, which prevents an error related to tinygradient

* Removed unnecessary indentation via lint
