Generate a msw mock server for testing

[jessekelly881]

It would be awesome for testing if effect-http could generate an msw server for testing purposes w/ fast-check arbitrary data. Or maybe just make it easier to create one yourself.

Hey, I don't know this one but it looks pretty cool 👍. As I don't have any experience with the lib and unfortunately I probably won't have a use-case for it myself right now, it would honestly take some time for me to get to it. That being said, if you have know the library and would be up for it, feel free to prepare a new package in this monorepo. We could expose it as a new effect-http-msw package. WDYT?
