Breaking Changes

• Change default solver to CaDiCaL by @celinval in #2557
  By default, Kani will now run CBMC with CaDiCaL, since this solver has outperformed Minisat in most of our benchmarks.
  User's should still be able to select Minisat (or a different solver) either by using #[solver] harness attribute,
  or by passing --solver=<SOLVER> command line option.
