refactor: Update wrong fluid fraction error message

[arng40]

Update this error message

***** ERROR
***** LOCATION: path/to/coreComponents/physicsSolvers/fluidFlow/CompositionalMultiphaseBase.cpp:939
***** Error cause: wrongSum > 0 l.925
***** Rank 6: compositionalMultiphaseFlow: component fractions do not sum to 1.0 in subregion 'cellBlock' for 342000 elements

Proposing some naming & information displaying improvements.

You must adapt the computation here:

Suggested change

	if( LvArray::math::abs( sumCompFrac - 1.0 ) > 1e-6 )
	localWrongSum += 1;
	localSupFrac += 1;
	if( LvArray::math::abs( sumCompFrac - 1.0 ) < 1e-6 )
	localInfFrac += 1;
	if( sumCompFrac > 1.0 + 1e-6 )
	localSupFrac += 1;
	if( sumCompFrac < 1.0 - 1e-6 )
	localInfFrac += 1;

• use a configurable tolerance? What do you think @paveltomin ?

[paveltomin]

fixed tolerance is probably ok

Suggested change

	GEOS_ERROR_IF( totalWrongCompFrac > 0,
	GEOS_FMT( "Component fractions go from {} to {} ( over {} elements ) in subregion '{}', but should always sum to 1.0",
	infFrac, supFrac, totalWrongCompFrac, subRegion.getName() ),
	getDataContext());
	GEOS_ERROR_IF( totalWrongCompFrac > 0,
	GEOS_FMT( "{} component fractions do not sum to 1.0 in subregion '{}'!\n"
	"{} are too low ; {} are too high ; component fractions sum range is from {} to {}.\n"
	"Consider adding field specification to initialize the '{}' field.",
	totalWrongCompFrac, subRegion.getName(),
	tooLowFracCount, tooHighFracCount, minFrac, maxFrac,
	/* globalCompFrac viewkey here */ ),
	getDataContext());

	RAJA::ReduceSum< parallelDeviceReduce, localIndex > localSupFrac( 0 );
	RAJA::ReduceSum< parallelDeviceReduce, localIndex > localInfFrac( 0 );
	RAJA::ReduceSum< parallelDeviceReduce, localIndex > localTooLowFracCount( 0 );

Suggested change

	localIndex const infFrac = MpiWrapper::min( localMinFrac.get() );
	localIndex const supFrac = MpiWrapper::sum( localMaxFrac.get() );
	localIndex const minFrac = MpiWrapper::min( localMinFrac.get() );
