feat: allow the option filename to be a function

[berthertogen]

Can we allow the filename and chunkFilename passed in trought the constructor to be functions instead of string only?

In our case it would make it easy to toggle the [hashcontent] for some bundles.
We would pass the option as followed:
filename: (chunk) => chunk.name === "NotHashedBundle" ? '[name].css' : '[name].[contenthash].css'

Might be worth noting that the latest version of webpack also supports something simular to this in their output.
eg: filename: (data) => data.chunk.name === "NotHashedBundle" ? '[name].js' : '[name].[chunkhash].js'

Ok, I'm on it.

Quick question, at the moment I can't get the tests passing, I'm getting Error: expect(received).toEqual(expected) but the expected and received printed out after this message seem to be the same.
My encoding is the same (utf-8), from what I can see its failing on carriage return. Any hint on how to get this fixed?
