support for individual .fsx files for F# inside sample folders

for F# examples might be useful to have invidividual .fsx scripts as they are more compact than full fsproj, would it be possible to support it? for example 

```fsharp
#r "nuget: FSharp.Data"
open FSharp.Data

type SomeJson = JsonProvider<"""{ "Hello" : "json"}""">
let myJsonSample = SomeJson.LoadSample()
```
