Stub http utils package

Things like:

• auto retries for failed requests
• auto json/text/binary parsing based on content type
• better instrumentation
• deduping
• etc

Can probably just use https://github.com/unjs/ofetch tbh, it has most of what we want baked in

Could also compose some things from @deno/std like https://github.com/denoland/std/blob/main/async/retry.ts

Given your comments, same thing mentioned in #17 . If we are just saying "use this npm package if you desire", is there an actual need for this to be a repo package? If so, is there enough to necessitate a stand-alone package?
