WorkspaceEdit doesn't support creating new files

[DanTup]

Not sure if this is a bug or just a missing feature!

I'm using WorkspaceEdit in my Code Actions provider but noticed that when a code action requires a new file (eg. creating a file from an import statement) it crashes because it can't find the file to modify (for both insert and replace).

I can't see anything on the API for allowing creation of new files, nor an easy way to detect if a file exists. I could obviously us node's fs class for this, but it seems a little weird to start doing that separate from the nice WorkspaceEdit class.

Is it valid to have WorkspaceEdit support creation of new files were required or is creating the files "manually" the expected way? I had a quick look at some other extensions (like TypeScript) but it seems like they don't handle it either (presumably none of their code actions need to create new files yet?).
