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.
