start_scan()` with no arguments was no longer returning anything. Now it's equivalent to `start_scan(Advertisement)` again. Fixes 75.

We have upgraded Pylint checks to use the latest version of Pylint and implemented usage of Black Python formatting. This does not change the functionality of the code - it is designed to bring it up to current standards and make it more readable.

* Remove pinned Pylint version number from build.yml file
* Synced `.pylintrc` file to match Adafruit standard
* Ran upgraded Pylint and applied any changes or new disables necessary
* Ran Black formatter and allowed application of changes across entire repo

The `AdafruitRadio` advertisement class was moved to https://github.com/adafruit/Adafruit_CircuitPython_Radio. One bug was also fixed. Because the API changed incompatibly, this is a new major version.
