Add progress reporting where appropriate

[Arlodotexe]

Progress reporting is a good call out. Generally the library is built so that progress reporting can be implemented application-side during an operation (e.g. navigating directories, moving things around, stream transfers). However, there's a few long-running extension methods where we could consider an IProgress parameter, such as Copy and Move.

Here is the inbox implementation for copying a file into a folder. Presumably, dotnet should supply us with an overload that takes an IProgress in Stream.CopyToAsync, but that doesn't appear to be the case. We'd need to build this ourselves or use one of the many versions that others have built.
