Fix import * in agipdlib
Description
Going through a few CI logs, I noticed that cal_tools/cal_tools/agipdlib.py was flagged a few times due to its from agipdutils import *.
This fixes that, as well as a few other pep8 violations.
No logic changes were introduced.
How Has This Been Tested?
This was tested by running python agipdlib.py to ensure that the file can be loaded fine.
