A Homebridge plugin for controlling/monitoring LG ThinQ devices via LG ThinQ platform.

/**
 * Represents a session for interacting with the LG ThinQ API.
 * This class is responsible for managing authentication tokens and session expiration.
 * It provides methods to check the validity of the session and update its properties.
 *
 * @example
 * ```typescript
 * const session = new Session('accessToken', 'refreshToken', Date.now() + 3600 * 1000);
 * if (session.isValid()) {
 *   console.log('Session is valid');
 * } else {
 *   console.log('Session has expired');
 * }
 * ```
