Release 0.2.0 (#10)

# Release 0.2.0

This release contains convenient helper methods that wrap Swift's Combine + URLSession and supplies an enjoyable and succinct developer experience to:

- Build and make requests
- Encode json Body
- Decode the Json Responses
- Handle Status Code Validation
- Return developer friendly errors to work with

## What is not in this release

All the desired helper methods `patch` `delete` etc.,

## Notes

The branch was titled `release1.0` by mistake.
