adding method to create set from keys of map of type comparable

[jay-babu]

I added github.com/google/gofuzz to do fuzzy testing. If you are against it, then I will remove the dependency and hardcode the test input, but that makes the testing less resilient.

I decided against adding a method to create a Set from values of Map. Happy to do so if you want

So, I am going to lean towards not relying on the fuzz library because we’re dealing with types purely designed within the Go language.

I would definitely be in support of GoFuzz if this were something along the lines of a protocol where fuzzing is definitely warranted to ensure proper parsing of inputs.

@deckarep should be good to go
