As ML.NET increases it's support for deep learning, we should add support for PyTorch models.
TorchSharp has bindings for LibTorch (PyTorch's C++ frontend) and offers the following functionality:

• Score models that were previously defined and trained in PyTorch's python API
• Define and train models directly in C#

We could have a scoring functionality similar to the TensorFlow scoring. We could also add training of Torch models defined in C#.
