Package reorganisation and conversion / filter separation

• Reorganise potentially reusable elements under a pm superpackage. This breaks back compatibility, and we are under version 1, so issued a minor version. Impacted:
• • loggen log generation
• • ssnap State Snap Miner
• • pmmodels Petri net and other model utilities
• Separate conversion and filtering in cgedq/conv.py, making reuse easier.
• • Add cgedq/regionmine.py, work in progress.

Switch to koalas for Petri nets

This minor release does internal reorganisation to depend directly on the koalas project, which provides lightweight process mining structures and functions in a Pythonic style. It is compatible with the more comprehensive and ambitious (pm4py)[https://pm4py.fit.fraunhofer.de/].

Earlier releases of statesnap-miner had forked versions of Petri nets and other data structures, which are now consolidated in a common project.
