Update mapping to support add'l topologies and specifications Support reading device information from a file. Support a star, include the ability to specify the index of the center qubit. Add device.computeAllPairShortestPaths() to all the device constructors. Print a better error message if the device is too small for the user's circuit. Create auxillary qubits if needed. Also remove them at the end of the pass if a subset (or all) of them did not end up being needed. Create a new mapping_v2p[] attribute so that downstream passes can determine exactly how the mapping changed the qubit placement. This will be particularly important for "observe"-type circuits that add measurements at the very end. Update tests
