Use static interfaces, remove AdHoc Encoding.

This will take advantage of static interfaces, which is the natural way of conding the IEncoding interface.

The question is what do we do with codec for interfaces which uses Ad-Hoc Encoding which relied in an instance to call the interface methods.

My feeling is that you could register multiple for the subset that you care about, why ad hoc encoding might be less useful in reality.

There was surprisingly few changes that I had to do in order to get it working with a sample project:
wallymathieu/auctions-api-fsharp#38

Well it seems only one in the code: Decode.Fail.propertyNotFound prop (o |> map (fun x -> x :> IEncoding)).
Which makes sense, because the old code was definitely wrong, the function should had always take care of the cast for you.
Actually I think if you used the 0.10.0 release you could had removed it.

I'll try it then 👍
