1.1.0 - Upgrade to latest Pylint, implement Black formatting

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

Initial Release: CircuitPython ATECC

CircuitPython Driver for Microchip's ATECCx08 cryptographic co-processors with secure hardware-based key storage. This library is based on the ArduinoECCX08 library.

• adafruit_atecc: Hardware/chip driver and interface
• adafruit_atecc_cert_util: Certificate builder utility. Currently supports generating a Certificate Signed Requests (CSR) but could be modified to generate/build a Self-Signed Certificate or JWS token.
• adafruit_atecc_asn1: *cert_util-specific ASN.1 tools and utilities for certificate generation.
  • Example of generating a Certificate Signing Request with this module
