Updating packages

1. Remember to make the changes against your up-to-date fork to avoid merge conflicts
2. Create a topic branch for your library rather than using the master branch
3. Edit the files
   • In minimum, update the +lib-version+ on build.boot
4. Check library changelog or such for clues if the API has been changed
   • Update externs (if the API has changed)
     • If the externs are generated, it is probably a good idea to always generate them between major and minor versions (major.minor.patch).
     • If the generated extern doesn't contain notes how it was generated, this is a good time add documentation
5. Run package script locally and test the package
   • If package uses latest Boot-cljsjs, also remember to commit boot-cljsjs-checksum.edn file
6. Commit with a message adhering to these guidelines
7. Create a pull request from your fork
