/**
 * Converts a font File into an Adafruit_GFX-compatible font File.
 *
 * @param inputFile - The input font File (TTF, OTF, WOFF).
 * @param pixelHeight - Desired font height in pixels. Values below 1 pixel, or values
 * that are not a finite number, fall back to a usable height. Defaults to 10.
 * @param format - Output format: 'file' for File object, 'string' for raw content, or undefined for FontPack object.
 * @returns A Promise that resolves to the output in the specified format (FontPack, File, or string).
