Tkinterdnd2

- Fixed an error in hook file due to the omission of a comma. I didn't do enough testing across systems.

- Fixed error in hook file which failed to account for new architechures.

- Removed support for Tix. Tix was depreciated in python3.6 and will be removed in python3.13
- Updated most tkdnd binaries from 2.9.2 to 2.9.4. ARM binaries are on 2.9.3 and need to be rebuilt (a problem I don't yet have a solution for)
- Updated hook.py to only include files for the appropriate platform.

- Updates to readme

- Original fork
