Open *.fcp file in FontCreator macOS version by default

Version: 16.0.3062

Reproduction:

  1. Install FontCreator.app
  2. Create an example project example.fcp
  3. Double click example.fcp

Expected:
FontCreator.app is started and the project is open

Actual:
TextEdit.app is started and the binary file is rendered as ASCII

Possible solution:

Define UTExportedTypeDeclarations in Info.plist such that macOS knows that *.fcp should be open by the FontCreator.app. Optionally, we can also provide a file icon such that *.fcp file stands out from other files.
