Duo Patch 2

Fix: download and ignore messages are now more consistent, with the currently downloading file name displayed in advance.
Info: you can now run welearn_bot --version or welearn_bot -v to display the installed version.
The project structure has also been reshuffled so that welearn_bot is no longer a script, but is instead called from the welearnbot.welearnbot module.

To make sure that you have this patch installed, run

pip install --upgrade welearn-bot-iiserkol
