Support back-pressure

[rogierschouten]

There seems to be no way to tell a Request to pause emitting 'row' events. This makes it impossible to stream query data onward without causing a large buffer somewhere. The node-mysql adapter for instance has the capability to return a NodeJS ReadableStream which supports back-pressure.

The issue is that Tedious doesn't currently support real streaming. @arthurschreiber started a stream based conversion in a pull request which would likely enable Tedious to support what you're looking for. Until that's completed, there's not really a good way to do what you're asking.

I'm going to close this, but feel free to continue discussion on the PR thread.
