Added legacy imports for older app code.

[reid-a]

Added stub functions to the zur.py file. These functions are imported but not used by the still-deployed version of the heterostructures app. Re-adding them here localizes the changes to a single repo. The long-term solution will remove both these stubs and the imports in the other repo, but this is a good near-term solution.

Hi @reid-a thanks for submitting the pull-request. Please run flake8, pycodestyle and pydocstyle with zur.py and see if it gives some error. Right now, the tests are failing because of the following reasons:

jarvis/analysis/interface/zur.py:448:1: E302 expected 2 blank lines, found 0 jarvis/analysis/interface/zur.py:451:1: E305 expected 2 blank lines after class or function definition, found 1

Also, you may have to add a docstring line to the modules, which you can find in an older version e.g.: https://github.com/usnistgov/jarvis/blob/v2020.7.4/jarvis/analysis/interface/zur.py#L373
