Implement io.Writer

[bramvdbogaerde]

The conn struct almost implements io.Writer, it only differs from the number of return values.

    *sse.Conn does not implement io.Writer (wrong type for Write method)
        have Write([]byte) error
        want Write([]byte) (int, error)

Is there a special reason why it is this way?
I think it would be useful to make the Conn implement io.Writer.

Thanks.

Sadly, the architecture makes it quite to hard to get the exact # of bytes written back to the initiating function call.

An option would be to return a fake value (e.g. 0) just for the sake of implementing the interface and trust that nobody is attempting to use it.

Will look into this tomorrow-ish, might find a way to cleverly implement it.
