Message.decode ignores length argument #78

Hi,

First of all, I'd like to say, awesome library, kudos any many thanks for writing this 😃 😃 😃

I think I've come across a bug when decoding a message. According to the documentation I can pass in a length to the Message.decode function. However, the length is ignored and instead it tries to decode the whole buffer.

This is the code:

As you can see, the length argument is not used anywhere in this function, nor passed along to T.decode(). This seems like a bug to me. Or am I missing something here?

Cheers,
Hein
