Face - DetectLivenessWithVerify SingleModal
Detects liveness of a target face in a sequence of images of the same stream type (e.g. color) and then compares with VerifyImage to return confidence score for identity scenarios.

BadRequest, Feature not enabled for subcription-id, please contact azure sales for more information.
BadRequest, Error in parsing multipart/form-data request, please check the example on the documentation website for reference.
BadRequest, Incorrect model-version. Please specify one of the valid model versions found at
BadRequest, A value for the 'Metadata' property was not provided. Required header example: Content-Type: application/json; charset=utf-8 Content-Disposition: form-data; name=Metadata
BadRequest, A value for the 'Content' property was not provided. Required header example: Content-Type: application/octet-stream; Content-Disposition: form-data; name=Content; filename=sample.jpg
