dualize the clique API to obtain independent sets, prove theorems about the dual relationship to cliques, dualize and add some theorems.
we only commit dual versions of theorems about the coclique number because we require them for a proof of mantels theorem. i have dualizations of most other theorems in the clique file, in case you also want those in this (or a subsequent) PR. give word if there are any other results you would like to see (maybe a refactor of graph partitions or a theorem about antichains?).
lemma compl_independentSet_meets_every_edgeandtheorem isIndependentSet_neighborSet_if_triangleFreeare also required for our proof and included in this PR, but might be too specific for mathlib.
