MNT: Change to a period separator for XTCE definitions
Browse files Browse the repository at this point in the history 
This updates the XTCE generator to produce a period between the
packet name and the mnemonic name, which helps for subsequent parsing.

Additionally, use that helpful fact to strip that leading packet name
in the packet_file_to_datasets routine.
