function PoolOptimizer::extractConflictConstraintsPerPackage

Disjunctive conflict constraints need to be considered in their own group. E.g. "^2.14 || ^3.3" needs to generate two conflict constraint groups in order for us to keep the best matching package for "^2.14" AND "^3.3" as otherwise, we'd only keep either one which can cause trouble (e.g. when using --prefer-lowest).
