This PR extends unknown function errors with a hint that suggests the closest function from the ones available based on the fuzzy string matching algorithm used to make similar suggestions. With this change, the example in #332 now also shows the help message Did you mean `ip`? in its diagnostics.
Resolves #332

This PR does not deal with #246, a similar request for methods instead of functions. But I'm planning on fixing it right after this one's cleared.
