Read the summary unit system from SMSPEC INTEHEAD, and fall back to vector
units for ESMRY files without SMSPEC. The unit system is read on first
request to keep summary import fast. Ensembles use the same realization as
for addresses. New RFT plots get the depth unit from their data sources.
A delta ensemble creates summary addresses for all realizations of the source ensembles. When a calculation was created after this, only the realizations showing tree nodes had their addresses recreated. The other realizations had no calculated address, and RimDeltaSummaryCase::values() discarded the vector as being present in only one of the source ensembles. Only realization 0 was plotted until the project was reloaded.
Add RifSummaryReaderInterface::refreshCalculatedAddresses() to recreate the addresses of the calculated readers without touching the native readers, and call it for all cases in an ensemble when calculations are updated.
