MVA evaluation: add doc + helpers for ROOT's SOFIE
SOFIE is a new interface (ROOT 6.26) for evaluating MVAs in ROOT: https://root.cern/doc/v626/release-notes.html#sofie-code-generation-for-fast-inference-of-deep-learning-models
It supports ONNX, Keras, PyTorch and is expected to be several times faster than the existing interfaces for non-batched evaluation of MVAs.
See RDF example here.
