Fixing wrong typing for ClusterWS.subscribe() method.

[b-a-byte]

Hi,

I recently faced an issue while creating a subscription with ClusterWS.subscribe() method. I'm using Typescript and the current typing of this method is "void" that makes the Pub/Sub example from README.md impossible to compile (TS2339: Property 'watch' does not exist on type 'void').

Thank you for your work, I appreciate working with ClusterWS ;)

Thanks for this, can you please create pull request to the branch next, we are implementing all changes and fixes in branch next . (new version will be ready soon)

I really like working with this framework, and soon we we will update all the guides (move it to wiki), new version will have a bit better performance and some improvements in typescript support.

Oh! I'm sorry for that.
I'm going to create another pull request to the proper branch.
