- Added reference module with test cases for JDK-provided readers

- Fixed ThumbsDBImageReader to pass test cases (got rid of some errouneous caching)
- Added TODO to remove caching in ICOImageReader (will need a test case for that)
- Minor changes in test cases to allow the reference test cases to pass
