Convert postman collection to OpenAPI spec

# @readme/postman-to-openapi

🛸 Convert Postman Collection v2.1/v2.0 to OpenAPI v3.0.

Or in other words, transform [this specification](https://schema.getpostman.com/json/collection/v2.1.0/collection.json) and [also this](https://schema.getpostman.com/json/collection/v2.0.0/collection.json) to [this one](http://spec.openapis.org/oas/v3.0.3.html)

## Differences from `postman-to-openapi`

There are some small differences between this library and the [postman-to-openapi](https://npm.im/postman-to-openapi) upstream:

* Does not ship with a CLI component.
* Has protections in place to prevent `undefined` statuses from being set.
* Has no `version` property on the exported method to determine which version you're running as this is unnecessary without a CLI component.
