Documentation build issues

[bgyori]

Currently the docs builds are failing due to two issues:

• Dependencies:

WARNING: autodoc: failed to import module 'construct' from module 'mira.dkg'; the following exception was raised:
No module named 'pyobo'

This would require (a) hiding the pyobo import inside some funnction, or (b) putting pyobo in as a requirement for the docs build to have it be installed (c) mocking pyobo.

• Jinja issues:

Traceback (most recent call last):
  File "/home/docs/checkouts/readthedocs.org/user_builds/miramodel/envs/latest/lib/python3.8/site-packages/sphinx/builders/html/__init__.py", line 1093, in handle_page

jinja2.exceptions.UndefinedError: 'style' is undefined

This implies some sort of incompatibility between Sphinx's RTD theme package and Jinja.
