Additional benchmark points for ggF->H3->(H_SM->tautau)+(H_singlet->bb)

The benchmark points correspond to the maximum cross-section times branching ratio
allowed in the NMSSM after experimental constraints from Higgs
boson measurements, searches for supersymmetry, B-meson physics and dark
matter detection as implemented in the used code NMSSMTools 5.5.0 [1]

These points are an extension to those provided in NMSSMBenchmarksMarch2020 for the process:

The cross section values used to produce the contours are tabulated below:

Linear interpolations of the 95%CL excluded cross-section*BR from [2] and of the max. allowed cross-section*BR from the previous table were then used to determine the boundary values of MHs. These boundary values are tabulated below:
