The README file states that CONFIG_VIDEO_BMP_GZIP behaves as follows:-

If this option is set, additionally to standard BMP images, gzipped BMP images can be displayed via the splashscreen support or the bmp command.

However, the splashscreen function *only* supports standard BMP images.

This patch adds the documented gzip support.
