Adafruit-circuitpython-neopixel

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 reverts the use of PixelBuf. It will be reintroduced once CircuitPython 5.0.0 is stable. This released is versioned as 5.0.0 because it removes an external dependency (adafruit-circuitpython-pypixelbuf) and we'll do a major release again when PixelBuf is reintroduced.
