3DSL v2020.0904 on 09/04/20

Bug Fixes

1. For SURVEILLANCE=ON, the %PV value written to the .wpv file sometimes contained ‘****’ rather than a number.  This then caused a restart SURVEILLANCE=ON run, based on the faulty .wpv file, to fail.
2. Wells on LASTSIMBHP at the first timestep of a restarted run would shut-in rather than remain open and reset to LASTVOI rate control, if their final rate control in the base run resulted in backflow.  This bug was introduced in the v2020.0821 version.

Enhancements

1. For PVTLIVEOIL keyword, added a check that oil compressibility above bubble point (column 5) must be greater than zero.
