v1.6.0

What's Changed

• v2 | CRSv4.3.0 Support by @troyxmccall in #13
• chore: version traefik and go to LTS by @troyxmccall in #14

BREAKING CHANGES

This would typically involve a v2 release, but traefik does not allow plugins over v1.x

https://community.traefik.io/t/failed-to-download-plugin/17155/2

• drop cached status code responses from OWASP, CRSv4 includes 500+ rules and many modern attack vectors involve cookies/headers, it is a security risk to cache these OWASP responses
• drop maxBodySize check as traefik already has built in middleware for checking bodySize
