Feature Request: Add lsof Command

[a-rookie-of-C-language]

Based on #56: “If they have an equivalent on either Linux or macOS, are commonly installed by default, and commonly used: Yes, absolutely.”

I’m proposing the implementation of the lsof command here. lsof (“list open files”) is a very commonly used command, and Windows does not provide a similar command. This is especially useful when I want to delete a file but the file is in use: the usual Windows methods for finding what is occupying the file are often cumbersome, while lsof can quickly identify the problem.

This can be implemented through the Win32 API, Windows Native API, NtQuerySystemInformation, NtQueryObject, etc. — at least, that is how we do it in the winuxcmd project. Of course, this requires administrator privileges; otherwise, the Windows kernel will deny access.

That actually doesn't sound like a bad idea at all. We need to draw a boundary somewhere since this project shouldn't include a bazillion commands of course, but I figure that lsof may be just as useful to SysAdmin as netstat is for network connections.
