Title: Accept an already parsed AST

This is a very specific feature that I needed to avoid repetition.
Since it was made to solve a very particular problem, feel free to close this ticket without accepting it, if you feel so.

I needed to analyze the AST before walking through the nodes, since I had the source, and the esprima's generated ast, it fell redundant to let falafel generate the AST again, so this pull request is only a way of using the options to provide an AST to falafel.
