/**
 * Makes a call to the OpenAI Images API to generate images based on a text prompt.
 *
 * This function provides access to OpenAI's image generation capabilities with support for:
 * - Different output formats (JPEG, PNG, WebP)
 * - Various image sizes and quality settings
 * - Multiple image generation in a single call
 * - Base64 encoded image data return
 *
 * @example
 * // Basic image generation
 * const response = await makeImagesCall('A beautiful sunset over mountains');
 *
 * @example
 * // Custom options
 * const response = await makeImagesCall('A birthday cake', {
 *   size: '1024x1024',
 *   outputFormat: 'png',
 *   quality: 'high',
 *   count: 2
 * });
 *
 * @param prompt - The text prompt describing the image to generate
 * @param options - Configuration options for image generation. Includes:
 * - size: Image dimensions (uses OpenAI's size options)
 * - outputFormat: Image format ('jpeg', 'png', 'webp') - defaults to 'webp'
 * - compression: Compression level (number) - defaults to 50
 * - quality: Quality setting (uses OpenAI's quality options) - defaults to 'high'
 * - count: Number of images to generate - defaults to 1
 * - background: Background setting for transparency support
 * - moderation: Content moderation level
 * - apiKey: OpenAI API key (optional, falls back to environment variable)
 * @returns Promise<ImageResponseWithUsage> - The image generation response with cost information
 * @throws Error if the API call fails or invalid parameters are provided
