Improved auto-formatter behavior

[charlestian23]

Description

After seeing the errors thrown by the auto-formatter in #776, I changed the auto-formatter's behavior:

• For pull requests into dev, the auto-formatter functions the same, though the method used for detecting formatting changes has been improved.
• For pull requests from dev, the auto-formatter will check if there are formatting changes that are necessary. Then, if there are formatting changes, the auto-formatter will open a new pull request with those changes into dev. This is because of branch protections, as the auto-formatter doesn't have permissions to directly push onto dev.

Note: The changes to GridRegion.java were made by the auto-formatter.

Type of change

• [x] Bug fix (non-breaking change which fixes an issue)
• [ ] New feature (non-breaking change which adds functionality)
• [x] Enhancement (improvement to an already existing feature)
• [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected)

How Has This Been Tested?

I tested these changes in my fork by mimicking the permissions of master and dev. I then created bad formatting commits both to and from dev to ensure that these changes work.
