Scan deps.edn for source-paths

[ericdallo]

Fixes #416

This should improve a lot the source-paths discoverability for deps.edn projects, checking :paths, :extra-paths and default configurable aliases :source-aliases (#{:dev :test}), keeping the source-paths fallback of #{"src" "test"}

Log example:
