Source maps need a fix

[davesmith00000]

From @Quafadas:

When trying to get source maps working in Indigo, I'm seeing this;

[Error] Cannot load file:///home/dave/repos/pkg/indigo/indigo/indigo/src/main/scala/indigo/shared/platform/SceneProcessor.scala due to access control checks.

Which I'm going to guess, is a reference to a local dev environment?

Could something like this could be preferable?
