libadsb-reader 0.1.50Fix1
=========================
- Durable collector outbox is now explicit opt-in via adsb_reader_config_t.durable_collector_queue.
- adsb-feeder enables durable_collector_queue automatically.
- Normal libadsb-reader / ADSB-RADAR mode keeps direct collector delivery and performs no durable_outbox INSERT/DELETE operations.
- durable_outbox is created only when durable mode is enabled.
- Feeder retains the 0.1.50 offline/restart-safe at-least-once delivery behavior.
