Add option to use a transform function

[bmancini42]

I was using this plugin and thought it would be handy to add an option for a transform function to operate on the path. I use something similar as a resolver plugin in webpack, but for my ava tests it made more sense to do it in a babel plugin. Interested in feedback re: whether or not you feel this belongs in your plugin.

This certainly seems interesting :) But instead of a PR I suggest opening an issue, because this needs more discussion. Things to consider:

• the signature of the function should probably be different, similar to getRealPath: not only the path to transform is important, but also the file where it is used
• maybe instead of a single transformer function a simple hook system would make more sense?

The important question here is: what could the transformer function do that getRealPath is not doing?

I won't close this, but I strongly suggest you go the way of a feature request instead.

Sure, will do

Added issue #165

Closing this for now as we need to discussed to find the best way to implement this
