feat: update to work with single fetch responseStub

[GuptaSiddhant]

Description

This PR is a POC (not expected to be merged). With the arrival of single-fetch in remix, I wanted to see this great project reflect the changes required.

It still may requires additional props like customStatus, etc.

Fixes #17

If this is a new feature please add a description of what was added and why below:

• Replace ResponseInit param with ResponseStub in all functions.
• Use ResponseStub to set cookie headers
• Either throw response for redirects or return bare object for json data.

Hey @GuptaSiddhant Thank you so much for htis PR, the reason I haven't yet implemented single fetch implementation is that it's still unstable and the last remix sprint planning Ryan and MJ confirmed a change to the api and the responseStub so I'm still waiting to see what comes out of it, but this is definitely the way with the current instance of unstable fetch!
