This repo would ideally need to be "rewritten"

Currently

```
$> du -scm .git/objects
9 .git/objects
9 total
```
which is too big for what it should be because various files which shouldn't be in git (venv , `__pycache__`) where committed. `testremote` branch already has them gone, but IMHO (earlier than later) with `git filter-branch` the whole history should be rewritten to shrink `.git/objects`

Start by comparing the current history with the testremote branch and inspect the oversized .git/objects directory, including the committed venv and __pycache__ files. Review the proposed git filter-branch history rewrite before making changes. Done means the unwanted files are removed from the whole history and the repository's .git/objects size is reduced.
