[encoding] BufferSource is not specified (#24)

https://encoding.spec.whatwg.org/#textdecoder -
```
USVString decode(optional BufferSource input, optional TextDecodeOptions options);
```
The BufferSource type is not specified anywhere.

ClosureCompiler insists it is Uint8Array -

MDN says it is an ArrayBufferView -
https://developer.mozilla.org/en-US/docs/Web/API/TextDecoder/decode#Parameters

This should be specified.

Perhaps http://heycam.github.io/webidl/#common-BufferSource (see https://github.com/whatwg/fetch/issues/108).
