The support for trailing $

[vmajsuk]

Hi!

In the webpack docs for resolve.alias there is an option to resolve a specific file by doing this:

resolve: {
    alias: { xyz$: 'path/to/xyz.js' }
}

, and then using it in the code like

import xyz from 'xyz'

However, that does not work with the plugin. What does work is to have a webpack config like this:

resolve: {
    alias: { xyz: 'path/to/xyz.js' }
}

, and using it like this:

import xyz from 'xyz'

This is caused by the following line in the src/index.js:176, I think:

let requiredFilePath = filePath.replace(aliasFrom, relativeFilePath);

I can submit a pr, but I'm just not sure what kind of behavior is expected. Maybe the correct way is checking if aliasFrom ends with $, and, in case it does and the path starts with aliasFrom.slice(1), do filePath.replace(aliasFrom.slice(1), relativeFilePath), so the module remains backward compatible? Or just add the description of the workaround to the README.md?
