Adafruit-circuitpython-bno055

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

For more information on using Pylint and Black on your code, check out [this guide on working with Pylint and Black](https://learn.adafruit.com/improve-your-code-with-pylint)

This release includes:
* Migrating this repository from Travis to GitHub Actions. This has no effect on the behavior of the code itself.

NOTE: This release has breaking changes

Breaking changes:
* `accelerometer` property has been removed, the equivalent non-deprecated property is `acceleration`.
* `magnetometer` property has been removed, the equivalent non-deprecated property is `magnetic`.
* `gyroscope` property has been removed, the equivalent non-deprecated property is `gyro`.

Non-breaking changes:
* If a property is disabled by putting it in a mode that it is disabled in, it will now return a tuple filled with `None` instead of a tuple filled with zeroes

Old behavior:

>>> sensor.mode = bno055.ACCONLY_MODE everything other than acceleration is disabled
>>> print(sensor.gyro)
(0, 0, 0)


New Behavior:

>>> sensor.mode = bno055.ACCONLY_MODE
>>> print(sensor.gyro)
(None, None, None)
