[FEATURE] Get/Set WorkCoord(工件坐标系) via RDK

Is your feature request related to a problem? Please describe.
使用element ui 设定比如moveL的目标点的时候，可以选定变量作为坐标系，但示教只能选世界/法兰/工具坐标系。

Describe the solution you'd like
rdk能够更新工具坐标系，或者示教可以选择COORD变量作为坐标系

Additional context
场景是机械臂是在移动平台上的，每次到位后机械臂和操作工件可能会有几厘米误差，所以需要校准。校准好后把工件坐标系通过rdk更新到机械臂，目前只能写入到全局变量中。
因为拖拽示教只能基于工件坐标系不能基于全局变量，所以录制动作/plan的时候都得先校准一遍，然后人手动在element里把全局变量中的坐标更新到工件坐标系里，然后基于工件坐标系录动作，体验很不好。

Cool, when will v1.5 be released? @pzhu-flexiv
