Merge feature/kalman, TMS_Bar and TMS_Kalman small changes

[LiamOS]

config/TMS_Default_Config.toml:

• FirstCluster now set to 'false' by default

TMS_Bar:

• Added GetBarWidth() and GetBarLength(), Width/Length are always the short/long bar dimension respectively

TMS_Kalman:

• cout and cerr output much more tolerable
• Check on initial Y slope for some tracks
• Better check on values while constructing nodes
• Can now handle horizontal (X) layers in theory, untested
• Detector noise matrix calculated using layer geometry (from TMS_Bar additions above)
• Chi2 calculated per-node, can be summed for a track

TMS_Reco

• SetStart/EndDirection is previously only called for tracks when Kalman was run, now set it as start-end (old way) if Kalman isn't run.

TMS_Track

• SetStartDirection/SetEndDirection now automagically normalise the vectors given to them.
• Chi2 variable added per track, to be filled by Kalman (in future maybe chi2_mu / chi2_amu?)

TMS_TreeWriter

• RecoTrackHitPos and related now include time, and thus have an extra index ([3] -> [4]).
• Added Chi2 to output files, filled by RecoTrackChi2 in TreeWriter.cpp

Should be behaving substantially better with this, but not perfect. Still leaves the detector sometimes. Want to wait for some feedback for Asa before tackling this fully.

The config change I fully approve. The Bar stuff looks reasonable. For the Kalman stuff I read through it, but I don't have the time to fully understand it, so I'll trust you on this

Validation plots from one file located in /exp/dune/data/users/losulliv/dune-tms/Validation/Reco_Tracks/MicroProdN1p1_NDLAr_1E18_RHC.spill.nu.0000120.EDEPSIM_SPILLS_TMS_RecoCandidates_Hough_Cluster1_images/

For future PRs, should we define some minimal set of required validation plots that should be presented, or do it depending on the content of the PRs?
