v0.19.0

Changes in this version:

• Media stream TCP tap (media_dump_base_port) — inspect the decrypted AA video/audio stream in VLC, mpv, etc.
  thanks: @korhojoa
• Added SWUpdate OTA (over-the-air) update support for all Raspberry Pi boards
  thanks: @Snirpo
• WASM scripting via wasmtime — write hooks that modify AA packets on the fly; disabled on ARMv6 (RPi Zero W)
  thanks: @Deadknight
• Key event injection (/inject_event) and rotary controller support (/inject_rotary)
• Speed data collection and /speed endpoint
  thanks: @Deadknight
• WebSocket support for the companion app — real-time sensor data streaming
  thanks: @Deadknight
• Odometer injection via REST API (/odometer)
• Tire pressure injection via REST API (/tire-pressure) — for head units that don't provide this data natively
• Media button interception on the HU — short press re-injects a clean click, long press triggers a configurable script (hu_button_handler)
  thanks: @Ioniq3
• TCP reverse bridge for SWUpdate, enables OTA updates from the companion app
  thanks: @Deadknight
• /version endpoint returning software version, board model and board prefix
  thanks: @Deadknight
• WASM scripts can call the local REST API (rest-call, rest-call-async) and push events over WebSocket
  thanks: @Deadknight
• /config-entry endpoint for updating a single config key without sending the entire config object
• Bluetooth: proper graceful RFCOMM shutdown before disconnect
  thanks: @Ioniq3
• SSL MITM: automatic fallback to non-MITM mode on SSL error (until restart)
  thanks: @juggie
