AustinMroz 6566acb406 Bundled subgraph fixes (#4964) ...

### Group support for subgraph unpacking
The unpacking code would silently delete groups (the cosmetic colored
rectangles). They are now correctly transferred.
### Fix subgraph node position on conversion to subgraph
Converting to subgraph will no longer cause nodes to inch upwards

### Make unpacking use same positioning calcs as conversion
Non trivial, but unpacking is now a proper inverse for conversion.

### Clean up old output links when unpacking
Unpacked nodes were left with dangling outputs. This would cause
cascading issues later, such as when consecutively unpacking nested
subgraphs.
### Minor refactoring for code clarity
