Add Writable

[SirkoS]

Can you please add a proxy for instances of stream.Writable ?

in particular I would be interested in the instances created by fs.createWriteStream()

How would mz proxy or improve on stream.Writable?

Both .write() and .end() accept a callback to be notified after the content has been flushed.
I had a use case, where I needed to wait until the stream had finished to proceed. The code would look much cleaner, if I could use await and/or promises.

unfortunately, that's a lot harder to do as we would have to create subclasses and extend methods, etc.

also, i generally recommend not interacting with streams directly and use a module that handles streams correctly and robustly
