Twist data structure in node storage for RRGraph
Using Tileable RR graph, each wire can have different ptc numbers (instead of only one). We are supporting this feature using node_twist_ data structure. However, we keep a single twist number for each rr node which is a lot of repeated data in node storage.
Proposed Behaviour
Long term solution would be to keep one twist number based on (x,y,layer) to avoid storing same twist number multiple time.
