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?

首先检查现有的 add_*() 包装器和 add_trace() 入口点，然后查看 issue #329，以确认预期的错误类型验证行为。确认哪些 trace 类型和属性仍缺少检查，并将完成定义为：对无效的属性类型引发错误，同时不破坏现有的必需属性检查。
