idea: Catch HorizonResultExceptions of result type ResultFsNonRealDataVerificationFailed

Browse Source 
- log a more clear error message as to what 2002-4604 means for the user
- and return the result from the FileSystemProxy IStorage to pass the invalid data handling to the game instead of stopping emulation there and then.
  - this may be changed. i'm pretty sure this error is only thrown when you actually have integrity checking enabled in settings, so maybe it crashing with a friendler message is more desired than potentially continuing execution. we will see
