New trx-noaa crate: FFT-based Hilbert transform (rustfft) for 2400 Hz
AM demodulation, sync A detection via cross-correlation, line assembly
at 4160 Hz, and JPEG output via the image crate.
- trx-core: NoaaImage type, DecodedMessage::NoaaImage variant,
noaa_decode_enabled/noaa_decode_reset_seq on RigState/RigSnapshot,
AUDIO_MSG_NOAA_IMAGE = 0x16
- trx-server: DecoderHistories::noaa, run_noaa_decoder task (activates
on noaa_decode_enabled, auto-finalises after 30 s silence), saves
JPEGs to ~/.cache/trx-rs/noaa/<YYYY-MM-DD_HH-MM-SS>.jpg, forwards
events over TCP audio channel and history replay
