AzulSCSI firmware version 1.0.0

The initial public release of AzulSCSI firmware. Hurray!

Owners with hardware version 1.1 (silk-screened on your AzulSCSI printed circuit board as 'AzulSCSI V1.1") Nearly all boards that are in public circulation are V1.1 boards. Don't load V1.1 firmware on your V1.0 board, and vice versa. The pinouts for the SD card socket is completely different between the two versions. V1.0 is SPI-only, V1.1 utilizes SDIO-only.
