[feat](trx-wxsat): rename trx-noaa to trx-wxsat with full NOAA APT decode

Rename the crate from trx-noaa to trx-wxsat (weather satellite) across
the entire workspace. Add full NOAA satellite decode support:

- Telemetry frame parsing: extract 16-wedge calibration data from the
  128-line telemetry frames embedded in APT lines
- Radiometric calibration: piecewise-linear LUT built from wedges 1-8
  to correct pixel values against known reference levels
- Channel identification: detect AVHRR sensor channels (VIS, NIR, MIR,
  TIR) from wedge 9 values per APT sub-channel
- Satellite identification: heuristic NOAA-15/18/19 detection from
  channel A/B sensor pairings
- Histogram equalisation: per-channel contrast enhancement for improved
  image output
- WxsatImage now carries satellite name and channel labels in decoded
  message broadcasts
