This PR adds a LRAT proof checker as an example application in examples/lrat_checker/.
LRAT is a proof format for SAT solvers.

Three verified applications are added:

  1. cake_lrat : LRAT checker implemented mostly in pure CakeML via translation
  2. cake_lrat_array : LRAT checker implemented with arrays + verified with CF
  3. cake_ramsey : this reads an LRAT file and checks that it is a proof of Ramsey number 4 = 18 i.e., its correctness theorem proves that Ramsey number 4 is 18 only if the checker outputs UNSATISFIABLE to stdout
