Adafruit-circuitpython-hid

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)

The HID objects now take a list of HID devices available and match themselves to the correct device. Previously, USB HID devices were used implicitly. Now, BLE HID devices can be used in place of USB HID.

Existing code will need to `import usb_hid` and pass in `usb_hid.devices` into the constructor of the object. For example `keyboard = Keyboard()` becomes `keyboard = Keyboard(usb_hid.devices)`.
