calculatorOptions not detecting.

[Anshal55]

Based on your work I am attempting to create a calculator to extract landmarks from faceMesh. I managed to get the calculator working but am struggling to create the calculator options. I am trying to figure out , in your sign_lang_prediction_pose_gpu.pbtxt you have defined "signlang.SignLangPredictionCalculatorOptions.ext" based on your .proto, Where have you defined the "signlang" base class from where the calculator option is being called? Thanks!
