Add augmenter tools for b-tagging objects

This adds a tool to apply b-tag "augmentation" to the b-tagging object before the NN based discriminant runs. The idea is that every input to the NN should be saved in a decoration to reduce the amount of room for error between training and application.

There's also a shell of a tool for muon related additions. I'm checking it in as well to give a starting point for the people who will implement that.
