That's one way to look at it:
 (a) NoiseSocket can provide a low-level padding for each Noise
transport message
 (b) The application could add extra padding into its own messages if
it needs it

I'm not sure whether (a) is worth doing in the NoiseSocket layer,
given that applications can always do (b) themselves.  E.g. in your
https/noise integration, you could just add the padding bytes yourself
for HTTP GET, but it wouldn't be part of NoiseSocket.

But I dunno, it's just a layering question.  You could try it and we
could see what API looks like.
