LoRa Scanner: a MeshCore preset, and its packets read

Browse Source 
- MeshCore joins the presets (EU/UK Narrow: 869.618 MHz, 62.5 kHz, SF8,
  CR 4/8, sync 0x12), after the Meshtastic ones so stored choices keep
  their number; `lora preset MeshCore` on the console
- lib/meshcore reads what MeshCore sends in clear: header, path, and a
  node's advert (name, kind, key, position)
- the list row, the details, a Capture's viewer and the console echo read
  a packet by the sync word it was received on
- the bandwidth is printed as 62.5, not 62

The radio only **listens**: nothing is transmitted. You need the **Cap LoRa-1262** and an **SD card**.
1. **Open the LoRa Scanner.** The Status Bar shows `L` while the radio listens.
2. **Pick a preset with <kbd>p</kbd>.** The Scanner offers the 7 Meshtastic presets allowed in EU868; LongFast is the default.
2. **Pick a preset with <kbd>p</kbd>.** The Scanner offers the 7 Meshtastic presets allowed in EU868 (LongFast is the default) and MeshCore.
3. **Wait for packets.** Each line is a packet: the time, RSSI and SNR, and for a Meshtastic packet the sender, the receiver and the hops. <kbd>Enter</kbd> shows a packet's header and its bytes.
4. **Press <kbd>c</kbd> to start a capture.** The Status Bar shows `CAP`. It keeps recording with the App closed.
5. **Press <kbd>c</kbd> again to stop.**
