Finally published a coverage-guided, native Lua fuzzing engine. I'll do some polishing before a first release, but it's ready for use now.

Some highlights: usage is quite similar to libfuzzer - define a fuzzing target and pass it to a function Fuzz, custom mutator can be defined as a Lua function, structure-aware inputs can be constructed using Fuzzing Data Provider (the same way as in libFuzzer). Moreover, added a code for building custom mutators in Lua for libFuzzer-based targets. Enjoy!

Would be nice to hear feedback!
