Add support for source maps

One of the most common project layouts is to have every function in it's own ps1 file. When one of those projects gets at a certain size (very large, like dbatools) that can begin to affect the load time of the module. As a workaround, some of these modules will "compile" the ps1 files into a single psm1.

I think it would be a good idea to come up with a source map system so if we break somewhere in the compiled psm1 we could show the original source file instead.

This could also be useful for other projects who test against the "fully built" version of their module in a Release folder. I do this in a lot of my projects and often end up editing the temporary version of a file in Release because that's where the debugger put me.

该 issue 没有指出任何文件、测试或入口点。首先定位模块编译和 debugger 的源位置处理，然后确定 source map 应如何将已编译的 psm1 位置连接到原始 ps1 文件。完成内容应包括明确定义的映射格式和 debugger 行为，并覆盖编译到 Release 文件夹中的模块。
