ffmpeg: Expose stdout callback to user

Integrating in homebridge/camera-utils#584

Would appreciate if we could do a new release once this is merged so I can use in my application.

@keur I'll go ahead and merge this, but I'm not sure we need to do a release just for this bump. Since we allow patch/minor updates for the @homebridge/camera-utils package, you should be able to install the latest version of that package and have ring automatically start using it.

@dgreif Thank you!

The way I call startTranscoding() has changed with this new callback option. I understand if you don't want to do a release for such a tiny API change. I'm fine pointing the package at git+https://github/dgreif/ring#main. In fact, I am doing that right now to point at my fork. However, I am including it from a JS project. That means I need to go into node_modules and manually build the ring-client-api package, then include the lib directory. My final include ends up looking like this: const { RingApi } = require('ring/packages/ring-client-api/lib')

It gets a little ugly. Is there a better way to do that? I don't program JS regularly, so apologies if these are basic questions.

EDIT: Nevermind. I just published the package to npm under my own username. So I have a workaround.
