Import a Gazepoint Biometrics export

Reads a Gazepoint CSV export containing biometric columns such as GSR, heart rate, interbeat interval, pulse signal, engagement dial, and TTL synchronization fields. The function is conservative: it preserves original column names, removes only empty trailing columns, and attaches a basic biometric-column summary as an attribute.

Path to a Gazepoint CSV export.

Values that should be treated as missing.
