Pigsty for VarVector doesn't have hash one hot

[rauhs]

I'm trying to convert my LearningPipeline to 0.6 static pipeline. I have some variable length features in my input instances.

With the pipeline I did:

new CategoricalHashOneHotVectorizer(nameof(TransportOrderInstance.PosAmount)) { OutputKind = CategoricalTransformOutputKind.Bag, Ordered = false, HashBits = 5},

What is the equivalent in the new static pipeline? The VarVector doesn't have a whole lot of extension functions. Shouldn't it also have OneHotEncoding? Though, it's not "One" necessarily.

This looks like an oversight on our part. We have OneHotHashEncoding for scalar and vector, but not for VarVector.

You can use CategoricalHashEstimator directly (via the dynamic API) until we fix that.
