Add add_*() functions for each trace type and provide error checking

• For example, add_scatter()/add_bar()/etc. These would essentially be thin wrappers around add_trace() with the proper type.
  • Throw errors for when required properties are missing. For example, add_scatter3d() requires x/y/z.
  • Throw errors for when a property is of the wrong type. See, for example, #329.

@timelyportfolio this would maybe be a good exercise if you're up for it?

先檢視現有的 add_*() 包裝器和 add_trace() 進入點，接著檢查 issue #329，以確認預期的錯誤型別驗證行為。確認哪些 trace 型別和屬性仍缺少檢查，並將完成定義為：對無效的屬性型別引發錯誤，同時不破壞現有的必要屬性檢查。
