Deno support

[jerrygreen]

Some popular packages, like Ramda, allow installation from Deno, - a js/ts environment, much more secure than NodeJS, made by Ryan Dahl, author of NodeJS (with ts being first-class citizen, with an integrated linter, test runner, and some very good docs...). Uhm... This is John Snow

It will require to remove all the NodeJS dependencies though, so it will barely possible, I presume. But still, I'd like to see it in Deno, so here's the issue anyway... :(
