De-duplicate Module.xml jar entries based on scope.

[benmusson]

The logic:

1. Group the manifests by jarName.
2. For each jarName, find all the scopes where it is applied and append them together in a list using flatMap.
3. Convert this list of scopes to a set in order to deduplicate, then join back together into a string.

At this point the de-duplication is complete and the original issue is resolved. #52

I think it would also be a good idea to force a sort order for the jars, so I added it in.

1. Sort by scope length (jars used in more places are listed first).
2. Sort by scope alphabetically
3. Sort by jarName alphabetically

Hi @benmusson , thanks for the PR. Can you add a unit test in WriteModuleXmlTest.kt?

@benmusson can you take a look at my stab in #56? I'll probably pull in a reviewer from our side too, someone who knows module dev, because I'm a build engineer.

My focus is too narrow. I can do stuff in Gradle and JVM languages but not have the bigger picture in focus.

One final (🤞 ) bit of ping pong after the module developers here weighed in. It's in my new draft PR #57 at the last commit 22946e2.
