feat: Visit parents of Lambda classes to catch potential inherited random generators

mbfreder commented 1 year ago

Issue #, if available: Issue #18

Description of changes:

Created a new detector that saves parent classes of lambda handlers so they can be visited by the main detector later to catch potential inherited random generators.
Updated the main detector to also visit parent classes of lambda handlers
Added tests to reproduce the issue and to make sure things are working properly

The approach in this PR does not cover cases for multiple level inheritance. We made the decision to only cover lambda handlers direct parent classes for now, while we investigate how we can cover multiple levels inheritance.

Update: added changes to cover multi-level inheritance.
