Bug fix release

It was identified that the v2.0 release was not working properly on Amiga 3000/4000 machines.

@salocinx did testing, discovered a bug, and implemented a bug fix.

This release contains that fix, and the sd card device driver has been tested to work on Amiga 3000/4000 machines.

Compiled files with eject/insert support

This release contains the software that is compiled to work with v2.0 of the design. Version 2.0 adds support for letting the AVR interrupt the Amiga, and is used to support eject/insert of the sd card.

• main.hex is the binary that should be programmed into the AVR.
• spisd.device is the device driver for the sd card module example.
