[XL] Change in pysim[master]: smdpp: add es2p interface + tests

Hoernchen has uploaded this change for review. ( https://gerrit.osmocom.org/c/pysim/+/40883?usp=email ) Change subject: smdpp: add es2p interface + tests ...................................................................... smdpp: add es2p interface + tests This adds the es2p interface, integrated with es9p, with some würgarounds to make the test mode work. It comes with a few basic tests to ensure it does not immediately break. This required some minor refactoring because the single file grew too large and linter and type checker kept complaining.
