chore(deps): update cloudflare to 0.13 and remove wyn patch

[Pablo1107]

Since cloudflare/cloudflare-rs#240 was merged upstream, we don't need the wyn patch, so update to 0.13 and remove the patch.

fixes #61

This also needs to removed the locked, zone_id and zone_name from the codebase. locked can be removed trivially, but I don't think the same applies to the other two.

Got it working, please review when available.

I don't know if cloudflare is moving too fast with their API changes but after Feb 05 21:40 UTC it started to break again even with this changes:
