Accustom

Build infrastructure needed some significant improvements. Much happier with this than 1.2.1


**Full Changelog**: https://github.com/awslabs/cloudformation-accustom/compare/1.2.1...1.3.2

This will be the last release for accustom, baring critical bug fixes and other management issues, until I rebuild accustom to use CloudFormation Registry resources.

This merges in the changes of issue 18 in as "Blacklist" and "Whitelist" have negative connotations, so needed to change them to something more acceptable. "Blacklist" and "Whitelist" will still work to preserve backwards compatibility with previous deployments written for versions 1.1.1 and earlier.

If "Blacklist" and "Whitelist" are used there will also be an error written to the logs at a WARNING level to inform users they need to move towards using "Allowlist" and "Blocklist"

Change from MIT license to Apache 2.0 license and add appropriate code headers. PyPi required a new version despite there being no code changes, other than comments, between 1.1.0 and 1.1.1.

1.1.0 Release Notes for reference as 1.1.0 has been yanked.
