Accept code from stdin

Is there a way to use `jscodeshift` with the standard input instead of with a file? (And print the result to stdout) For example:

```
cat index.js | jscodeshift -t transform.js > transformedIndex.js
```

This kind of flexibility is very useful in any tool, but I personally would like to have it to be able to pipe code from vim to `jscodeshift`.

If this is not possible at the moment, is there any chance to have it in the future?

Thanks.
