Reports objects (data object including) that implement java.io.Serializable but don't implement readResolve

Example:

import java.io.Serializable

  object Foo : Serializable

The quick fix implements readResolve method:

import java.io.Serializable

  object Foo : Serializable {
      private fun readResolve() = Foo
  }
