Add a basic write test for WOZ images #138

Closed iflan closed 2 years ago

The new test just tries to change some random nibbles at the beginning of the image and then verifies that the change has been recorded. This exposed a bug where q7 was never set to true when write mode was toggled on.

Also, the assumptions and limitations of moveHead are more clearly documented.
