Fuzzing: Advanced tools

[Nicceboy]

Re-implement some tasks to include some programmatic fuzzing on scale

With at least:

• https://llvm.org/docs/LibFuzzer.html
• https://github.com/google/centipede
• https://github.com/rust-fuzz/cargo-fuzz

LibFuzzer is no longer developed and Centipede has been merged into https://github.com/google/fuzztest
