Reworked cable connections (#3334)

* Reworked cable connections

Added enums for cable variants and sizes.
Rules for connections between a cable and another cable or grid member
are much more simple without any exceptions for certain combinations.
1/ Connections are rendered as the lowest type between cores.
2/ Each type uses are core for clear separation.
3/ The core will always be on the cable with the higher order.
