automatically adding @Override annotations

[lbergelson]

Description

added the @Override annotation everywhere it was missing using auto inspection

also cleaned up a few typos in LittleEndianOutputStream and made a protected variable private since it's a final class

The lack of @Override annotations was annoying me so I just had intellij fix them all. Maybe it will prevent future bugs do to ham-fisted refactorings.

Checklist

• Code compiles correctly
• New tests covering changes and new functionality
• All tests passing
• Extended the README / documentation, if necessary
• Is not backward compatible (breaks binary or source compatibility)
