[checkerframework]

A bit of a shadow feature because the checker framework folks need to do some work on their side.
this update makes lombok generate a few checker framework annotations (if configured to do so)
which let the checker framework add warnings and errors for example if you misuse builders, or ignore
the return values of withers, etc.
