1.0.0-M6

• Update to Dotty 0.26.0
• Fix #32 resolve parameters in structural types (#66)
  This allows polymorphic usage of Tags with structural types, e.g. the following will now work correctly:

  trait Typeclass[A] { 
    type Out
  }
  
  def tagFor[A: Tag, B: Tag] = 
    Tag[Typeclass[A] { type Out = B }]
  
  tagFor[Int, String].tag == Tag[Typeclass[Int] { type Out = String }].tag // true
  // `A` & `B` type parameters were substituted for Int & String in `tagFor`

  This also allows Tags for higher-kinded TagK's, which are encoded using structural types, to be resolved correctly and allows polymorphic injection of TagK's in distage modules:

  def moduleWithTag[F[_]: TagK] = new ModuleDef {
    addImplicit[TagK[F]]
    make[Unit].fromHas(
      (tag: TagK[F]) =>
        // (tag: TagK[F]) parameter no longer causes an error 
        zio.console.putStrLn(s"Got TagK[F]=$tag")
    )
  }
