ClusterFuzzLite: Continuous Fuzzing for All

Here's a simple way to think about fuzzing. If you're not fuzzing your interface to find vulnerabilities, someone else is.

Super nice to extend their oss-fuzz services to everybody. I'm already using oss-fuzz, but will add this to my GitHub actions for many other projects of mine. You just need to be able to compile your C project with clang++. oss-fuzz has more fuzzers, but libfuzzer is good enough.
