As agreed in team meeting - you can merge this first version to keep trace of it
(knowing it will evolve)

There is now a "notes=M" for MFA

Looks fundamentally good (at least at the design level)

[1] IMHO you should clean up the style before the first commit:

$ pip install pycodestyle
$ pycodestyle --max-line-length=500 logconv.py

reports lots of issues (mostly about spaces) (BTW: I ignored the long line because IMHO keeping the long error message in a single line is painful but more readable and less error prone than splitting them)
[2] You should also create a specific man page and modify the spec file so that logconv or logconv.py get delivered in the r (that said, you may decide to delay these two changes in a future commit)
[3] Command should start with #!/usr/bin/python3 as our other python commands
[4] the global constant dicts should probably better be uppercase
