Add a co2brine pvt model

The CO2BRINE model is activated by setting CO2STOR in the RUNSPEC section

The CO2 and brine pvt properties are computed based on pvt models in opm-material
- CO2 density is from Span and Wager (1996) as given in co2table.inc
- CO2 viscosity is from Fenhour et al (1998)
- Brine density and viscosity is based on H20 + correction based on Batzle and Wang (1992)
- H20 density is from Hu et al (2007)
- H20 viscosity is computed from density based on correlation given in IAPWS 97

At the current stage the oil-phase is used to model the brine. If a proper gas-water
simulator is made, the Brine PVT should be moved to the water phase.

Known limitations:
- Currently the viscosity of the Brine does not depend on the composition
- Salinity is assumed to be constant and given by SALINITY [mol/kg].
