Added list support with prefix functionality

[tmayr]

Added support for list() and kv.list({ prefix }) as per the cf docs

Let me know if any changes are needed.

EDIT: Updated code, it's list not browse

Hey, sorry I never saw your PR when I filed #130. I've got an implementation of cursor, and list_complete over there. Do you think we could combine them together in this PR?

[tmayr]

Hey @GregBrimble

Yeah sure thing!, you can make PR on my branch I guess? Or I can make the changes, lmk what you prefer.

Any chance of this being merged in?

@tmayr , apologies, I totally missed your reply back in October.

@thetre97 , I think this repo has been abandoned now (see the README.md), but Cloudflare's wrangler tool now has the dev command, which lets you locally test a worker. Personally, I have been using it instead of cloudworker for a while now.

Ah, I had seen the preview command, but not the new dev command. Thanks!
