Prosimos packages structure

[iharsuvorau]

There's an issue with how Prosimos sets up its packages, https://github.com/AutomatedProcessImprovement/Prosimos/blob/main/pyproject.toml#L8-L10. At the moment, when we run pip install prosimos, the command installs three standalone packages:

• cli
• prosimos
• bpdfr_discovery

Instead, we should make all those packages children of prosimos. Or, at least rename cli because it's confusing to have a global package named cli in a Python environment:

Also, bpdfr_discovery probably has to be removed completely from the distribution.
