Add `selectByIdsTracked` (fix #45 )

[oyvindberg]

This is built on top of #94 . Enables very convenient usage with things like ZQuery

  override def selectByIdsTracked(stateprovinceids: Array[StateprovinceId])(implicit c: Connection): Map[StateprovinceId, Option[StateprovinceRow]] = {
    val byId = selectByIds(stateprovinceids).view.map(x => (x.stateprovinceid, x)).toMap
    stateprovinceids.view.map(id => (id, byId.get(id))).toMap
  }

  override def selectByIdsTracked(stateprovinceids: Array[StateprovinceId]): ConnectionIO[Map[StateprovinceId, Option[StateprovinceRow]]] = {
    selectByIds(stateprovinceids).compile.toList.map { rows =>
      val byId = rows.view.map(x => (x.stateprovinceid, x)).toMap
      stateprovinceids.view.map(id => (id, byId.get(id))).toMap
    }
  }

  override def selectByIdsTracked(stateprovinceids: Array[StateprovinceId]): ZIO[ZConnection, Throwable, Map[StateprovinceId, Option[StateprovinceRow]]] = {
    selectByIds(stateprovinceids).runCollect.map { rows =>
      val byId = rows.view.map(x => (x.stateprovinceid, x)).toMap
      stateprovinceids.view.map(id => (id, byId.get(id))).toMap
    }
  }
