Basic technic network-ng compatibility

[S-S-X]

This is to provide minimum compatibility for new technic network system described here: mt-mods/technic#96

Full network move compatibility proposal here #79 (should actually be draft) but that one is not even nearly mvp, it is poc that still needs significant amounts of work.

Maybe remove unnecessary cleanups, currently this will not check if networks inside and outside of jumped area actually comes into contact but instead destroys caches for all networks around jump target location.

I've updated the test-server to technic:network-ng and pulled this branch too, works all well so far 👍

I jumped around with my new "mobile home" that consists of several jump-units and i split some networks and reassembled them again. It contained MV and HV circuits with solar supply, a few batteries and machines.
