• [x] Build is successful
• [x] Code is cleaned up and formatted

SNAG: PyPI doesn't accept packages that declare dependencies using direct URLs. This means we'd have to get delphi-logger hosted on PyPI.

Closed in favor of #1486

Actually, gonna convert this PR to switching the server and acquisition code to use delphi_utils as in George's comment.
