Mapbox Java SDK v5.4.1

This release is the exact same as https://github.com/mapbox/mapbox-java/releases/tag/v5.4.0 and it targets the ls-release-5.4.0 branch. This release is being made because CircleCI wasn't able to send some artifact files to Bintray during the release process, so this release is another attempt to get CircleCI and Bintray to successfully work for all of the Java SDK's modules.
