should respect rebar3 src_dirs and project_app_dirs options

[KunaPrime]

in more complex projects it is valuable to be able to search for references in different places

Hi @KunaPrime , would you elaborate on what this would mean?

[KunaPrime]

rebar3 is searching for project source files in project_app_dirs configuration
and if i override this, plugin can not find include paths correctly
this could also happen due confinguring base_dir (option that changes build location)

It sounds sensible to add support for these.

Would you be interested in contributing? The Contributing section gives a few pointers about it.
