Quark/gluon fractions from MC in TauFakes training samples

Evaluation of the quark-originated and gluon-originated jets for the training samples employed for tau fakes estimation. This improves the
estimated value. Now evaluating systematics
Fixed charged Higgs row labels in summary table

Replaced TBH and HTB with the explicit mention to the decay channel
New tau fakes estimate

This uses quark/gluon originated jets fractions in order to improve the estimate
New tau fakes computation

Added infrastructure for estimate which takes into account quark/gluon jets structure.
The calculation of the fractions must still be done by hand. Working on that.
Updated paths for tau fakes stuff

List of the different paths I personally use.
