[ENH]: Add NIfTI storage

[omidvarnia]

Are you requiring a new dataset or marker?

• I understand this is not a marker or dataset request

Which feature do you want to include?

Add a nifti storage for the extraction of voxel-wise features such as ReHo and f/ALFF

How do you imagine this integrated in junifer?

Necessary for storing voxel-wise feature maps

Do you have a sample code that implements this outside of junifer?

No response

Anything else to say?

No response

I would like to have proper use-cases of why this has to be included in Junifer's functionality.
