v1.5.0: Add support for Gecko scalars (#96)
* Rename the Gecko output file for Kotlin This additionally changes the function to get the Glean type from the Gecko histogram name from `get` to `getHistogram`. * Move scalars out of the histograms mapping * Bonus: fix import ordering in ktlint * Don't declare functions as 'operator' * Extend test coverage * Make flake8 happy * Make black happy this time :)
