unused protocols/fuzz-testing

[jbesraa]

reviewing the codebase we can find a few crates that are not used neither by any other crate nor in the ci. we should decide what we do with those.

First one to discuss is protocols/fuzz-testing.

While I like having fuzz testing very much, I personally dont have the capacity to maintain this now nor make it usable as a start. I also dont see it being used in the CI. I would suggest to remove it if no one is willing to give it attention and reintroduce it once we are ready to add fuzzy testing.

I suggest to not remove them we can still run them locally and this justify the very little mainteinance needed
