Add Topologies for 16-GPU gfx942 SuperNode (#1417)

* Add Topologies for 16-GPU gfx942 SuperNode

- Add GigaIO topologies to tools/topo_expl for dev and testing
- Add GigaIO Columba 16 GPU romeModel and adjust topology
  matching algorithm in rome_models for 16 GPU system
- Fix bug which failed to match Rome Model when using subsets
  of system resources (i.e. ROCR_VISIBLE_DEVICES is set)
- Fixes for topo_expl

* Fix bug w/ 1H16P
