Improved DevEX with Flattened SDKs

Speakeasy has introduced a new flattened structure for its SDKs to enhance the API developer experience by simplifying the process of interacting with APIs. This updated structure abstracts the complexity of distinguishing between query parameters, path parameters, headers, and request bodies, allowing users to provide necessary data as key-value pairs. This change results in less code for users to write, more comprehensible interfaces, faster integration times, and an overall improved developer experience. The transition to this new structure is seamless for users with automated pipelines and requires a simple upgrade for those using the CLI.
