Add a 5-strike scrubber to the CLI

Consider adding a 5-strike scrubber to the CLI application.

This would render a file non-decodable if the wrong original file or wrong password are used 3 times. This would ideally be something that is configurable.

My thoughts for this function being that if someone were attempting to crack the password used to decode a file, or attempting to find the original file used to decode the file, the function would render it impossible to decode the file. This would prevent any efforts to brute force break the password, for example.

Upon reflection, I think 5 strikes will be more reasonable than 3.
