Add option to sort candidates by pT in Unified Particle Transformer

[stahlleiton]

PR description:

This PR adds a flag to allow to sort by pT the PF candidates and lost tracks used as input features in the Unified Particle Transformer tag producer. While studying the performance of UParT b-tagging in heavy-ion simulations, it was found that sorting the input candidates by pT improved the performance in the most central (0-10%) PbPb collisions.

The flag to sort the candidates by pT is set to false by default, so no changes are expected in the standard configuration.

PR validation:

Tested using ttbar PbPb simulations.
