CountFeatureSelection transform doesn't work with text

[yaeldekel]

It uses a generic CountAggregator class which requires the type to be IEquatable, and ReadOnlyMemory is not IEquatable. It doesn't seem like Equals() is used anywhere though, so I think this constraint can be removed.

Is this new? I've used CountFeatureSelection (in MAML) very often.

This is a regression caused by the switch from DvText to ReadOnlyMemory.
