two different relative paths have same ID

Say I have a node module `a` that has `require("../compiled/templates");` along with a node module `b` that has its own `require("../compiled/templates");` - both pointing to their own respective `templates.js` file. When I use this on bundle-collapser, I get the same ID for both files, even though they're different files (i.e. they should have two different IDs). This leads me to believe that the ID generated is based off the uniqueness of the string, and not the full absolute path of the file that is required.
