Integrate FAA registry info

[mhostetter]

The FAA publishes a list of all registered tail numbers, their registrants, and their corresponding ICAO addresses, among other things. The CSV list is updated daily and is about 60 MB. I want to one-time convert a downloaded copy to a SQLite database for fast lookups.

• Write a script to convert a user's downloaded FAA registry CSV file into an ICAO-indexed SQLite database
• Add option to ADS-B Decoder to use FAA database
• Propagate registry number info in decoded bursts
