ModuleNotFoundError: No module named 'nibabel.trackvis'

Based on https://nipy.org/nibabel/changelog.html#api-changes-and-deprecations, a number of elements in the API were removed in the latest 4.0.0 version released on Saturday 18 June 2022. This includes nibabel.trackvis.

Code should be modify to incorporate those changes.
