`@delegate` does not properly forward type aliases

[Atry]

package myPackage

import macrame.delegate

object Foo {

  type AnySeq = Seq[_]

  def emptySeq: AnySeq = Nil

}

object Bar {

  @delegate
  val underlying: Foo.type = Foo

}

object Main {

  def main(args: Array[String]): Unit = {
    val x: AnySeq = Bar.emptySeq
  }
}

/private/tmp/TypeDelegate/TypeDelegate.scala:23: type AnySeq is not a member of object myPackage.Bar
    val x: Bar.AnySeq = Bar.emptySeq
               ^
one error found

It would be great if @delegate creates a type AnySeq = Foo.AnySeq alias

As per the documentation, @delegate forwards method calls. I would accept a PR to add this behavior though.
