octave-jnifti binary package in Ubuntu Jammy amd64

 This is a fully functional NIfTI-1/2 reader/writer that supports
 both MATLAB and GNU Octave, and is capable of reading/writing both
 non-compressed and compressed NIfTI files (.nii, .nii.gz) as
 well as two-part Analyze7.5/NIfTI files.
 .
 More importantly, this is a toolbox that converts NIfTI data to
 its JSON-based replacement, JNIfTI (.jnii for text-based and .bnii
 for binary-based), defined by the JNIfTI specification
 http://github.com/fangq/jnifti. JNIfTI is a much more flexible,
 human-readable and extensible file format compared to the more
 rigid and opaque NIfTI format, making the data much easier to
 manipulate and share.
