[Request] Cursor option for QPEEK command

Hello,

I'm currently working on a node [task-queue module](https://github.com/GitbookIO/node-tasqueue) using disque.
It would be great to have a CURSOR option (actually, acting more like a SKIP options) for the QPEEK command. This would allow to paginate through a whole queue easily when using a UI with disque.
Let me know if this is something that could be done.

Kind regards,
Johan
