encodeHandle

[kirelagin]

There is already a function to save yaml to a file (encodeFile) but it doesn’t help when I need to save something to a handle (e.g. if I got one from withTempFile).

I think it might be a good idea to change Text.Libyaml.{encode,decode}File to work with a handle.

P.S. In the specific case of withTempFile for some reason just writing to the same file with encodeFile works, while writeFile fails. I have no explanation for this. Might it be a bug somewhere?

I'm OK with adding such functions, PR welcome. I'm guessing encodeFile works because it's following a different code path for opening the file descriptor, as it's passing the content over to the libyaml C library via the FFI and not using Handles.
