Function parse_calibrations 

pub(crate) fn parse_calibrations(
    raw: &SensorConfig,
) -> HashMap<u8, CalibrationSpec>

Parses dashboard calibration map keys into numeric LabJack channels.

Invalid channel keys are ignored after logging because one malformed calibration entry should not prevent unrelated channels from being archived.

Arguments

• raw - Sensor settings whose calibrations map is read.

Returns

Calibrations keyed by channel number. Empty when the section has no calibrations map.
