Bootloader use compressed fonts: The previous Bootloader was larger than 128k => not fitting into the first sectors of the second flash bank. Most memory is occupied by the two fonts in use. In order to make the bootloader small enough for the bootloader update function the fonts need to be compressed. To avoid code changes in visualization functions the compressed fonts are decompressed into RAM and then used in the same way as before.
