This change implements a "Remote CDM" mode that allows the CDM to operate without a local Widevine Device (.wvd) file. Instead, it delegates the license handling to a third-party server by exchanging JSON messages. Changes: - Add `serde`, `serde_json`, and `base64` dependencies. - Add `remote_cdm` toggle to `OpenWvConfig` and enable it by default. - Implement `RemoteRequest` and `RemoteResponse` for JSON communication. - Update `Session` to handle Remote mode challenges and updates. - Allow `OpenWv` initialization and instance creation without a device identity if Remote mode is enabled. - Update `build.rs` to automatically create an empty `embedded.wvd` if missing, satisfying the compile-time `include_bytes!` requirement. - Add unit tests for Remote CDM session creation and update.

This comprehensive update introduces a Remote CDM architecture for OpenWV, allowing the CDM to function without a local device identity (.wvd file) by delegating license processing to a remote server. Key additions: - Remote CDM protocol: Exchanges JSON messages containing init_data and service certificates via the host application. - `server.py`: A Flask-based server using `pywidevine` that performs the actual Widevine license requests and returns content keys. - Configuration: Added `remote_cdm` toggle in `src/config.rs`. - Decoupling: Modified the build process to allow compilation without a real `embedded.wvd` file. - Robustness: Added support for passing service certificates to the remote server and updated unit tests to cover the new protocol. The Remote CDM mode ensures that sensitive device private keys are never exposed on the client machine, satisfying the security requirements for distributed CDM deployments.

Implemented Remote CDM mode which allows using a third-party server for license handling, removing the need for a local embedded.wvd file. Added necessary dependencies, updated session and initialization logic, and ensured the project builds without a valid wvd file. Added unit tests for the new functionality.
