[Enhance] FSharp support

[bradphelan]

When added to an fsharp project there is an error about CodeDom missing. Not surprising but is there a chance support can be added?

Actually the error is weird. I have some fsharp projects but Nerdbank.Gitversioning is not installed. I get

676 Warning(s)

but it doesn't say which assembly and there is nothing else in the log

NB.GV already has some support for manually generating source code when CodeDom is absent, since this is required for dotnet build. So yes, I think F# support could be added.
As I'm not an F# syntax expert, I'd prefer to add this by way of accepting someone else's PR.

Ahhhh. Ignore my previous post about the error still being there even though the FSharp projects didn't include the nuget package. That was some weird stuff that hasn't happened again. But I created a pull request anyway to at least put the name of the assembly in the error messages. :)

I might add stuff for FSharp if it turns out I need them.
