Describe the bug
The same TIFF file cannot be parsed when the file extension is .tif. The parser returns an error: Unsupported file type. However, when the file is renamed to have a .tiff extension, it parses successfully. This suggests that the parser may not recognize .tif as a valid TIFF file extension.

Additional context
Reproduction steps:

  1. Upload a valid TIFF image file with the .tif extension using the API.
  2. Observe the response error: Unsupported file type.
  3. Rename the exact same file to have a .tiff extension.
  4. Upload the renamed file using the same method.
  5. Observe that the file is successfully parsed.
