the fields found in later "data" responses.
### hx71x/dump_hx71x
This endpoint is used to subscribe to raw HX711 and HX717 ADC data.
Obtaining these low-level ADC updates may be useful for diagnostic
and debugging purposes. Using this endpoint may increase Klipper's
system load.
A request may look like:
`{"id": 123, "method":"hx71x/dump_hx71x",
"params": {"sensor": "load_cell", "response_template": {}}}`
and might return:
`{"id": 123,"result":{"header":["time","counts"]}}`
and might later produce asynchronous messages such as:
`{"params":{"data":[[3292.432935, 562534], [3292.4394937, 5625322]]}}`
### pause_resume/cancel
This endpoint is similar to running the "PRINT_CANCEL" G-Code command.
