Mark science/esys-particle as BROKEN (not just on 13)
The upstream bug report is from may 2019, reporting this:
/wrkdirs/usr/ports/science/esys-particle/work/ESyS-Particle-2.3.5/Model/ElasticInteractionGroup.h:55:19: error: no candidate function template was found for dependent friend function template specialization
friend ostream& operator<< <>(ostream&,const CElasticInteractionGroup<T>&); ^
/wrkdirs/usr/ports/science/esys-particle/work/ESyS-Particle-2.3.5/Foundation/vec3.hpp:305:27: note: candidate ignored: not a function template

This now happens on 12.1 as well.
