Define a stable automatic module name.

[brunchboy]

@brunchboy would like to modularize the project lib-carabiner but is unable to do so because edn-java does not define an automatic module name. See this article for a very good explanation of why this is necessary. All the other lib-carabiner dependencies already do this, so as soon as edn-java does, it will be possible.

This pull request sets us.bpsm.edn as the automatic module name, which makes sense as it is likely the module name you will use if you ever decide to modularize this project itself.

Thanks for considering this change.
