Please, support authenticated mirrors

[UnaiUribarri-TomTom]

The company I work for has a policy that mandates using an authenticated secured mirror for all artefact requests.
But this package does not support such mirrors, getting 401 responses like this:

Workaround: migrate from SBT to Maven/Gradle or create a Maven package that contains just the proto files.
