Standalone AIP Generator Fails

[nutjob4life]

Describe the bug

Running the AIP Generator aipgen fails on every platform.

To Reproduce

1. Install Python, such as Python 3.8.5 for Windows from the Python website.
2. Create a virtual env with it: python -m venv mypy
3. Go to it: cd mypy
4. Install PDS Deep Archive Scripts\pip install pds.deeparchive
5. Run it on a nice nearby bundle file: Scripts\pds-deep-archive ..\mybundle\bundle.xml (or equivalent).

Expected behavior

I expect it to work, buh. That is, aipgen should make the AIP and associated files, not give this stack trace:

Traceback (most recent call last):
  File "C:\USers\seanc\Documents\pds\pds-deep-archive\bin\aipgen-script.py", line 12, in <module>
    sys.exit(pds.aipgen.aip.main())
  File "c:\users\seanc\documents\pds\pds-deep-archive\src\pds\aipgen\aip.py", line 392, in main
    process(args.bundle, args.args.include_latest_collection_only, con, ts)
AttributeError: 'Namespace' object has no attribute 'args'
