Circle shape removal breaks API

The shape type 'circle' was removed in this version https://github.com/ashiguruma/patternomaly/commit/c32a840cbaff5338365cff8f759540be57519e0c

This was an API breaking change. The major version number should have been bumped but wasn't. That or we should support the use of 'circle' and 'disc'.
