Support '#!/usr/bin/env ts-node' scripts

[rektide]

Hello. I like being able to run my scripts locally, they usually have a little short main() function they run if they are run directly.

At the moment, if I create a short script & run tspath -f throws, tspath seems to not be able to work with it:

TSPath 1.3.7

}

Example dist/config.js:

#!/usr/bin/env ts-node
console.log("hi!")

Some general description of using ts-node to make scripts directly runnable, the technique i'm trying to use, is in this great write-up: Shelling with TypeScript.
