Support http(s):// gateway URLs

[lidel]

Current state

Users need to know how to convert HTTP gateway URLS to ipfs:// and ipns:// to be able to benefit from verifiable retrieval. This is error-prone, and encourages people to reinvent conversion code over and over again.

Feature request

It should be possible to pass http(s):// URLs that follow either path gateway or subdomain gateway spec, or single DNSLink name gateway, and get verified Response back for relevant /ipns or /ipfs content path.

First user of this feature will be service worker gateway, which needs {redirect:'manual'} to return meaningful redirect as a fix for ipfs/service-worker-gateway#62

I think this has been implemented by #4
