Implement ability to extract network traffic (CAN, LIN, Ethernet, etc.) from VSA message records on disk. Add a method to Device class that uses the VSAParser and the individual record types to extract messages from the VSA message records and pass them back to the communication system. This routes messages such that it appears as if they were discovered live instead of read from disk. The parse process (in Device) requires determination of metadata about the VSA file system on a device before it can begin extracting messages. This currently only handles data captured from the current coremini script on a device.
