[FR] Don't process hidden [*]Dependencies.xml files

[vizgl]

Feature proposal

I use custom build script with many conditions. For some builds I want to remove libs. I made it by setting hidden flag on folders to true. In that case unity don't add scripts, resources etc to the final apk file. But EDM is not process such cases. It still read [*]Dependencies.xml files and add *.aar files.

I propose add check for parent folders / files to match hidden flag to false before process it.
