Upgrade Fable to Nagareyama

[alfonsogarciacaro]

@Shmew I didn't try it yet but I think with Fable 3 we can get rid of the compiler directives to avoid type testing with generics like:

      #if !FABLE_COMPILER
      match g with
      | :? GenerateCont<'a> as g -> GenerateCont<_>.Bind (g.Generator, (fun () -> GenerateCont<_>.Bind (g.Cont(), cont)))
      | _ -> (new GenerateCont<'a>(g, cont) :> AsyncGenerator<'a>)
      #else

Some problem with #if here

Error: /home/runner/work/FSharp.Control.AsyncSeq/FSharp.Control.AsyncSeq/src/FSharp.Control.AsyncSeq/AsyncSeq.fs(1749,1): error FS0521: No #endif found for #if or #else [/home/runner/work/FSharp.Control.AsyncSeq/FSharp.Control.AsyncSeq/src/FSharp.Control.AsyncSeq/FSharp.Control.AsyncSeq.fsproj]

@alfonsogarciacaro I'm closing this, I think it needs to be re-done
