This PR adds official compatibility with Ruby 3 and removes the existing Appraisal based testing in favor of more manual testing to enable better exercising of multiple Ruby versions. In addition, we migrate away from Travis CI because they want money and I don't have it :smile_cat: This PR also establishes 1.9.0 as the lower end of the supported ruby versions (and will therefore represent a major version number bump).
