Fails to load with Scalafmt 1.5.1

Plugin works with 1.4, but using scalafmtVersion := "1.5.1" I get:

The org.scalafmt.config package is not public API, neo-sbt-scalafmt should follow the recommendations I made here #36 (comment)
to use the following methods
https://github.com/scalameta/scalafmt/blob/4a5b7681933fa1a1c289d5fa5aa8a4abfe8a71c9/scalafmt-core/shared/src/main/scala/org/scalafmt/Scalafmt.scala#L77-L89

I created a fix for this #72 . Comments, ideas?
Would love to get this in shape.

Would it be possible to get the above PR merged and released?
