UFO energy per layer

This MR provides the energy per layer information for UFOs, and adds it to JETM1. This is necessary for deriving the GSC/GNNC with these jets, which is why this is labeled urgent.

Currently, the energy per layer is computed for all UFOs where there is a cluster linked to any PFOs used to build the UFO. As far as I can tell, we have this information for neutral and combined UFOs, but not the UFOs made from charged PFO.

I have done some basic checks on the output, and it looks like the sum of the energy per layer typically adds up to around 33%, which makes sense if we are missing the charged PFO components.
