libadsb-reader 0.1.45
=====================

Performance release for ADSB-RADARBOX.

- Aircraft standing data are bulk-loaded once at startup into the legacy
  sorted_collection RAM index and sorted by numeric ICAO24. Runtime aircraft
  enrichment and adsb_standing_has_aircraft() no longer query SQLite.
- SQLite remains open read-only for flights, airlines and ICAO24 country ranges.
- Added decoder-side output coalescer / pre-sorter:
  * repeated callsign, altitude, speed, heading and squawk values no longer
    generate downstream messages;
  * decoded aircraft state is always updated;
  * motion-only changed state is emitted at most 4 Hz per aircraft;
  * callsign and squawk changes bypass the rate limiter;
  * pending changed-field bits are accumulated until the next emission.
- RTL-SDR diagnostics now report emitted and suppressed output rates.
- Existing 8192-frame RTL-SDR producer/consumer queue and queue statistics from
  0.1.44 are retained unchanged.

The public ABI is unchanged apart from the reported library version.
