Adding support for Interconnect Nodes

- Required changing the ScanCode node datastructure
- Interconnect Id's must be stored until the end as it's not possible to calculate the max per node ScanCode until after all the assignments are complete
- Should make future additions more straight-forward (that require per ScanCode information to be stored)
