Hi In [commit](https://github.com/TeamWertarbyte/material-ui-rating/commit/427f4b943196af8ec1ae83a943d02c4f2fef30f7#diff-ee45f72452795d9c3dc4273b2179f76aL24) was broken change which don't mark how broken. Icon classes don't work and now i can't set size for icon svg. [Demo](https://codesandbox.io/s/18n6q9mqrl) Also docs have old information [see code](https://mui.wertarbyte.com/#!/Rating/9) I would like to return this opportunity.
