TIFF file read checks only look for ".tif" extension, missing files with ".tiff" extension.

Tiff file loads and checks for type of config and UI entries (folder vs file) rely on ".tif" extension and can't handle ".tiff", ignoring it or treating it as a folder.

Let me know if you want me to add tests for this in test_files.py
