Why is this PR needed?

What does this PR do?

• Adds validators for VIA JSON files and COCO JSON files for untracked data
• Adds test for validators
• Adds movement as a dependency

TODO:

• Should the validation associated with ValidVIAUntrackedJSON include the JSON file validation and the general file validation? ---> Use inheritance
  • add tests to check that the children actually run the parent's validations
  • I want the children to run additional validations on the attributes. Is this a good idea? See this SO post.
  • I used a solution suggested in this issue
• For file specific validations, add a check that verifies the schema defines types for the required keys.
  • otherwise if the schema has all keys that are not present in the input file, it will still pass the validation
