V30: Add support for Fujitsu MSP55LV100S N64 repros and fix bug in Serial Monitor filebrowser
- The Fujitsu MSP55LV100S consists out of two Fujitsu MSP55LV512 which themselves are just Spansion S29GL256N flashroms. One flashrom is used for the high byte the other for the low byte. - You can now browse pages with the Serial Monitor's file browser just like you can with the OLED.
