Test of 2q3g 2L (NNLO) finite remainder amplitude squared
Contributions are
  LO:   B  = 0l*0l
  NLO:  V  = 1l*0l
  NNLO: VV = 2l*0l + 1l*1l
Checks ratio (r) and relative difference (d) of NJet C++ implementation against reference point from arXiv:2102.13609, where
  r(a,b)=a/b
  d(a,b)=|(a-b)/b|
Tests that d < 0.001
