class SimpleCov::SourceFile::Statistics

downstream consumers don’t have to special-case enable-state.
during the run — disabled or empty criteria collapse to 0/0/0 so
for a SourceFile, regardless of which criteria were actually enabled
Builds the ‘CoverageStatistics` triple (`:line`, `:branch`, `:method`)
