Possibility of adding lume.deepclone

[Greyvy]

Hey there,

Not sure if you’re still working on this repo at all or what, but I figured I would give it a shot. I’ve been using lume on a small game I’ve been working on, very handy little library, big fan so far.

I ran into a case where I needed to make a simple clone of a table, and the lume.clone out of the box only does sub tables by reference, which was a bit of an issue in the code I was working on.

After doing a little bit of research I found a couple of very sane ways of doing a bit more thorough cloning. If you are up for having a deepclone, or even just replacing the current lume.clone, I would be happy to shoot you a pull request.

Let me know what you think, and thanks again for the excellent library!
