Scalafix rule to exclude specific implicits

Scalafix rule to exclude specific implicits

This project attempts to solve SO question: Exclude a specific implicit from a Scala project

Scalafix can inspect synthetic code such as inferred type parameters, implicit arguments, implicit conversions, inferred .apply and for-comprehensions.

TODO: Replace the inefficient implementation which uses String.contains with perhaps ApplyTree.
