  and 'Use finite-fault model from the USGS', making it possible to convert
  a wider set of ruptures from the USGS data
• A sanity check was added to make sure that the hypocenter is inside the
  surface of the rupture. Otherwise, it is relocated to the middle point of
  the surface and a warning indicates the original and translated
  coordinates.

[Christopher Brooks (@CB-quakemodel)]

• Added ability to specify z1pt0 and z2pt5 as -999 within site model
  to inform (basin term considering) GMMs to use their own vs30 to
  z1pt0 or z2pt5 relationship to estimate these site parameters, in
  effect preventing additional adjustment to GMM basin terms based
  on unknown site information. QA tests (classical case_89) + unit
  tests (utils_infer_basin_params_test.py) added
