Function liveLabJackChannelSubject

liveLabJackChannelSubject(config: LabJackSubjectConfig, channel: number): string
Builds the live-data subject for one LabJack channel.

Legacy configs give <root>.<asset>.data.chNN, with the root used as configured and the asset padded to three digits. Structured configs give <root>.<site>.<box>.<source>.live.chNN with every token sanitized. Missing values fall back to unknown-site and unknown-box, and the source falls back from source_id to labjack_name to asset<NNN>.
Parameters
- config: LabJackSubjectConfig
  LabJack config.
- channel: number
  LabJack channel number.
Returns string
The subject the streamer publishes that channel's FlatBuffer Scan messages on.
Example
```
liveLabJackChannelSubject({ nats_subject: "avenabox", asset_number: 1456 }, 11);
// "avenabox.1456.data.ch11"
liveLabJackChannelSubject({
  nats_subject: "avenars", asset_number: 1456,
  site_id: "i69", box_id: "i69-mu1", source_id: "i69-lj2",
}, 11);
// "avenars.i69.i69-mu1.i69-lj2.live.ch11"
