Grid import using opm-common improvements (#11438) * Update opm-common EGRID reader to support LGRs, NNCs, dual porosity, unit system info and time step filters * Rearrange well reading code into separate class * Update resdata library to not require an ecl_grid when reading well information. Only lgr names are needed, allows reused by opm_common reader
