Avoid 0xFF character when writing to MAX7456 in auto-increment mode
The 0xFF character is used as an "escape" character by the MAX7456 when using auto-increment mode. The last byte of the characters used for the logo is the 0xFF character and this was causing the version and CMS instructions to not display.
Changed the logic to avoid the 0xFF character during the auto-increment phase and added a second pass if needed to update those characters in direct addressing mode.
