Add gzipped logo support
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. Signed-off-by: Mark Jackson <mpfj@mimc.co.uk>
