New Features / Improvements

added XST to modem_sim
more descriptive error messages and OWTT/latency and distance information
Ping replies that have timed out will now publish ping_reply on topic even though it does not have a transaction for it anymore.
packet_dispatch handles empty packets and zero padded packets (only effects logging)
modem_location_sim added non-default simple_path option for rng to create simple path track that keeps modem sims close
added feature to handle partial packets (which can happen when sim_packet_performance_node/fixed_frame_error_rate >0.0)
interpolates the frame_success masks to the size of the packet being processed, finds the first bad frame and clears the rest of the packet (like acomms_driver_node.py then publishes the truncated packet)
sim_packet_performance.py now populates miniframe_success in SimPacketPerformanceResponse, currently hard coded to succeed (only the dataframe rate is being passed to this service call at the the moment)

Bugfixes

sim_packets that are part of a ping transaction get a shorter duration (0.5) compared to other packets
