Fix to V2 Protocol for Fuse/Sig/Lock byte read -- off by one error on the array when writing back the response from the device.

FLASH/EEPROM reading and writing currently broken and unfinished, respectively.

* \section SSec_Description Project Description:
*
* Firmware for an AVRStudio compatible AVRISP-MKII clone programmer. This project will enable the USB AVR series of
* microcontrollers to act as a clone of the official Atmel AVRISP-MKII programmer, usable within AVRStudio.
* microcontrollers to act as a clone of the official Atmel AVRISP-MKII programmer, usable within AVRStudio. In its
* most basic form, it allows for the programming of 5V AVRs from within AVRStudio with no special hardware other than
* the USB AVR and the parts needed for the USB interface. If the user desires, more advanced circuits incorporating
* level conversion can be made to allow for the programming of 3.3V AVR designs.
*
* This device spoofs Atmel's official AVRISP-MKII device PID so that it remains compatible with Atmel's AVRISP-MKII
* drivers. When promted, direct your OS to install Atmel's AVRISP-MKII drivers provided with AVRStudio.
*
* Note that this design currently has several limitations:
* - Minimum target clock speed of 500KHz due to hardware SPI used
* - No VTARGET detection and notification
* - No reversed/shorted target connector detection and notification
*
* \section SSec_Options Project Options
*
* The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
