 * Load face-landmarks-detection.
 *
 * @param pkg - The name of the package to load, e.g. 'mediapipe-facemesh'.
 * @param config - a configuration object with the following properties:
 *  - `maxContinuousChecks` How many frames to go without running the bounding
 * box detector. Only relevant if maxFaces > 1. Defaults to 5.
 *  - `detectionConfidence` Threshold for discarding a prediction. Defaults to
 * 0.9.
 *  - `maxFaces` The maximum number of faces detected in the input. Should be
 * set to the minimum number for performance. Defaults to 10.
 *  - `iouThreshold` A float representing the threshold for deciding whether
 * boxes overlap too much in non-maximum suppression. Must be between [0, 1].
 * Defaults to 0.3.
 *  - `scoreThreshold` A threshold for deciding when to remove boxes based
 * on score in non-maximum suppression. Defaults to 0.75.
 *  - `shouldLoadIrisModel` Whether to also load the iris detection model.
 * Defaults to true.
