Merge Module Specs

The question is broadly:
- What and How to merge into single PSM1?

I can see the following challenges:
- Some Folder structures may be different
- Some people may add things to their psm1 stub
- Using statements needs to be gathered/unique'd and inserted at top of psm1
- Requires should be added in module manifest (except Admin)
- Classes should be imported in a certain order (where to define it?)
- Classes should be imported before functions
- Extra data should be merge-able (say if you provide a scriptblock? Thinking out loud)
- should the non-merged files be copied? and everything merged deleted, empty dir deleted as well?

Am I missing anything?

首先检查 issue 中列出的模块文件夹结构、PSM1 存根、using 语句和模块清单要求。确定合并规则、导入顺序，以及对额外数据和未合并文件的处理方式，然后在开始实现任何内容之前，与项目维护者确认预期结果。
