[feature request] Add section in README comparing nelua with "competing" alternatives (V-lang, ...)

[earizon]

Feature motivation

Most of us have a very limited time ( < 60 secs) to look at new (promising) projects in Github.
Adding a comparative to similar projects can boost attention to visitors like me.

Feature description

Add table comparative to similar projects (V-Lang comes to my minds in the sense that it offers a language with a light-weight syntax and native C speeds).
