This introduces the most basic functionality for doing fuzz testing of a property in K.
It adds a function
fuzzto thektool.kfuzzpyk module which takes the location of an llvm-kompiled definition, a template configuration in kore containing input variables to be randomized, a strategy for substituting those variables (so far, only with integers usingkintegers), and either a function to check the resulting kore or a flag to check the exit code of the interpreter. It will invoke hypothesis to randomize the inputs and run the interpreter.
