Simplification of the tau quality cuts

Simplification of the quality cut class, that gets rid of the "boost" dependence and allows further extension of the interface to accept also packedCandides from miniAOD (not implemented yet, but work-in-progress). No change in physics output expected. The PFTau sequence can be somehow faster.

This change is already implemented in 71x and 72x, so in principle it is a backport. 

The 71x request is #2843. There is no 72x request, as this one was included already in 71x pre-releases. It is not a full backport of that PR, but only the clean-up of quality cuts that is essential for the miniAOD tools development.
