/**
 * Converts a JPG or PNG image to monochrome bitmap format for printing
 *
 * The Memobird API requires images to be in monochrome bitmap format.
 * This endpoint converts standard JPG/PNG images to the required format.
 *
 * @param client - Got HTTP client instance
 * @param ak - Access Key
 * @param imgBase64String - JPG or PNG image as Base64 string
 * @returns Promise resolving to converted image response
 * @throws {APIError} If API returns error response
 * @throws {NetworkError} If network request fails
 *
 * @example
 * ```typescript
 * const jpgBase64 = '...'; // Your JPG image
 * const response = await convertToMonochrome(client, ak, jpgBase64);
 * const monochromeBase64 = response.result;
 * // Now use monochromeBase64 for printing
 * ```
