[ML.Net, c#] LightGBM re-training and Importing LightGBM CLI/MPI model

[wil70]

1. Can I retrain LightGBM? 1.a. I tried via AutoML and it seems to start from scratch when I do a FIT or I call MLModel1.Training.cs " public static ITransformer RetrainPipeline(MLContext mlContext, IDataView trainData)" auto generated code. 1.b. In the documentation "Re-train a model", LightGBM is not listed as re-traine-able? 1.b.1. is it still true (asking as the documentation is 9 months old)? TY! 1.b.2 I can see from Python or even XGBM c/c++ you can retrain? using init_model option of lightgbm.train
2. Can I use the model generated by LightGBM CLI/MPI in ML.net? Thanks!
