Bootloader uf2/cdc should run even without SD flashed #30

improve stability by making the bootloader uf2/cdc running even without SD. The work is already 90% done, the rest is setting that bootloader pull from the SD, MBR etc ... e.g SD size to flash to appropriate address etc ... it should use default one ( e.g SD 6.1.0 known size in case SD is not flashed).

Once the bootloader without SD (or corrupted) can be put into known good by dfu-flash with an pre-built binary in the bin directory.
