Replace Travis CI with CircleCI (#80)

* Removes support for Ruby <= 2.5
* Removes support for RBX
* Sets required ruby version to >= 2.6
* Adds code quality checks with Code Climate for target version
* Adds Ruby version checks for >= 2.7
* Pins simplecov to version ~> 0.21.0 to make the rest-reporter work
