Logging warnings when first import

[Sheile]

Summary

When import parser in addresslib first time, I'm getting same warning that is #196
When import next time, warnings aren't displayed.

IMO, The parser is working correctly.

Reproduce

1. uninstall flanker

% pip uninstall -y flanker
Uninstalling flanker-0.9.0:
  Successfully uninstalled flanker-0.9.0

2. install flanker

% pip install flanker
...
Installing collected packages: flanker
  Running setup.py install for flanker ... done
Successfully installed flanker-0.9.0

3. import and get warnings

4. import and DON'T get warnings

Remarks

Python: 3.7.4
flanker: 0.9.0

flanker 0.9.8 is working without warnings.
Could you release 0.9.8 to PyPI?

pip uninstall -y flanker
pip install git+https://github.com/mailgun/[email protected]
python -c 'from flanker.addresslib import address'

We're using flanker 0.9.11 in AWS Lambda (python3.6) and still seeing these warnings

[marban]

In case this has been fixed in 0.9.12, could you release the package?

[n3storm]

It is not solved.

Python 3.5.3 debian
Pip install from git and I get same output.

The problem is we are using flanker in a postfix transport and error returns as a mail delivery error.

I'm also curious why this triest to create files on my system after launch:

Couldn't create 'flanker.addresslib._parser.mailbox_parsetab'. [Errno 13] Permission denied: '/usr/lib/python3.10/site-packages/flanker/addresslib/_parser/mailbox_parsetab.py'

Felt extremely sketchy.
