/**
 * The Controller client for Controly.
 * This class is used for clients that need to control one or more Displays.
 * It connects to the server, subscribes to displays, sends commands, and listens for status updates.
 *
 * @example
 * ```javascript
 * const controller = new controly.Controller({
 *   serverUrl: 'ws://localhost:8080/ws',
 *   id: 'my-remote-controller-A',
 * });
 *
 * controller.on('open', (id) => {
 *   console.log(`Controller connected with ID: ${id}`);
 *   controller.subscribe(['display-01']);
 * });
 *
 * controller.on('command_list', (commandList, fromDisplayId) => {
 *   console.log(`Commands from ${fromDisplayId}:`, commandList);
 *   // Dynamically build a UI based on the commands
 * });
 *
 * controller.on('status', (status, fromDisplayId) => {
 *   console.log(`Status from ${fromDisplayId}:`, status);
 *   // Update the UI with the new status
 * });
 *
 * controller.on('display_disconnected', (displayId) => {
 *  console.log(`Display ${displayId} has disconnected.`);
 *  // Remove the UI for the disconnected display
 * });
 *
 * controller.connect();
 *
 * // Later, to send a command:
 * controller.sendCommand('display-01', {
 *   name: 'set_volume',
 *   args: { level: 90 },
 * });
 * ```
