[Feature Request] Detect duplicate requires

[jwoertink]

This is probably a rare case, but I just found in lucky we had some duplicate requires in the same file.

require "./thing"
require "./stuff"
require "./thing"  # <-- would be neat if Ameba caught this
require "./other_stuff"

Nice one. I wonder why the compiler doesn’t detect this

[jwoertink]

That's a good point. I think it just returns false if it's already been required. So maybe the compiler doesn't know the difference between "I can't require this" and "I've already required this"? ... though, I guess if it couldn't require it, it would just raise a compile-time error 🤔
