I'm experiencing significant delays when trying to open NIFTI files in the .nii.gz format using Fiji.

Steps to Reproduce:

1. Open Fiji.
2. Use File > Import > Bio-Formats to select a .nii.gz file.
3. The message "Identifying .nii.gz" appears, but the application hangs for several minutes before the Bio-Formats import configuration window finally shows up.
4. Alternatively, using File > Import > Bio-Formats windowless results in the same delay.
5. Using File > Open... shows "Initializing base reader" in the UI, but again, the application hangs for a long time.

In ImageJ 1, drag-and-drop or File > Open... loads my .nii.gz NIFTI stack within seconds.
