Hello John. running ``` pyvips.base.get_suffixes() ['.csv', '.mat', '.raw', '.v', '.vips', '.ppm', '.pgm', '.pbm', '.pfm', '.hdr', '.dz', '.png', '.jpg', '.jpeg', '.jpe', '.webp', '.tif', '.tiff', '.gif', '.bmp'] ``` Gives the available suffixes that pyvips understands. In your guide https://libvips.github.io/libvips/install.html it states that "If available, vips can load and save NIFTI images." I ran `sudo apt-get install libnifti2` (new package i guess) but still .nii and .nii.gz doesnt show up. Do i need to link it somehow?
