Bad import - icdiff.get_options

Description of Issue/Question

The code for icdiff doesnt seem to have this function anymore get_options

Line 19 in 6a882ee

from icdiff import diff, codec_print, get_options, ConsoleDiff

  File "/opt/prelude/modules/jsnapy.py", line 4, in <module>
    from jnpr.jsnapy import SnapAdmin  # pylint: disable=import-error
  File "/usr/local/lib/python3.8/site-packages/jnpr/jsnapy/__init__.py", line 83, in <module>
    from jnpr.jsnapy.jsnapy import SnapAdmin
  File "/usr/local/lib/python3.8/site-packages/jnpr/jsnapy/jsnapy.py", line 22, in <module>
    from jnpr.jsnapy.check import Comparator
  File "/usr/local/lib/python3.8/site-packages/jnpr/jsnapy/check.py", line 19, in <module>
    from icdiff import diff, codec_print, get_options, ConsoleDiff
ImportError: cannot import name 'get_options' from 'icdiff' (/usr/local/lib/python3.8/site-packages/icdiff.py)

I can reproduce by just attempting to import the icdiff functions

>>> from icdiff import diff, codec_print, get_options, ConsoleDiff
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name 'get_options' from 'icdiff' (/usr/local/lib/python3.8/site-packages/icdiff.py) <---
