Forward Tagger Energy Correction Function

[asligonulacar]

Implemented the Forward Tagger energy correction function as an IGUANA algorithm. Please let me know if I have made any errors. This is mainly a placeholder until a more complicated algorithm can be implemented. This function is currently only validated for Fall 2018 outbending data.

Do you need ROOT dependence for this algorithm? I plan to add it soon...

We now allow algorithms to depend on ROOT; however, try to use the new ROOT::Math vectors rather than TLorentzVector. The updated LorentzTransformer algorithm demonstrates a boost with ROOT::Math::Boost.

Some other things of note:

• add your algorithm to src/iguana/algorithms/meson.build so that it's included in the build; if it depends on ROOT, set needs_ROOT to true
• add your name to the CODEOWNERS file and attach it to your algorithm's files

Hi folks,
What is the status of the iguana FT correction ? It looks like this has not been merged yet, and there is a test fail. Does this need some work ? I would like to try out this algorithm.
Cheers

@dglazier it needed some work to catch up with the main branch. I updated this algorithm and spot checked the output, but it needs validation, in particular a "Validator" type algorithm (see, e.g., MomentumCorrectionValidator which makes plots of the corrections from the MomentumCorrection algorithm).

@asligonulacar can you check the new version of your algorithm, and would you be willing to write such a validator?
