Cannot import aocxchange.step_ocaf

[copyrite]

I can't seem to import aocxchange.step_ocaf. For comparison, import aocxchange.step will work just fine. The error I receive is this:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<frozen zipimport>", line 259, in load_module
  File "C:\tools\miniconda3\envs\REDACTED\lib\site-packages\aocxchange-18.0.10-py3.6.egg\aocxchange\step_ocaf.py", line 15, in <module>
ImportError: cannot import name 'Handle_TDocStd_Document' from 'OCC.Core.TDocStd' (C:\tools\miniconda3\envs\REDACTED\lib\site-packages\OCC\Core\TDocStd.py)

The erroneous line is here.

aoc-xchange/aocxchange/step_ocaf.py

Line 15 in 93aae93

from OCC.Core.TDocStd import Handle_TDocStd_Document

I've tracked this down to PythonOCC's side and apparently there has been an effort to remove "Handle_" prefixes from namespaces: tpaviot/pythonocc-core#583

Don't know yet if I actually need step_ocaf for my use case but thought I should notify.
