Upgraded the Raspberry Pi 4 firmware of Niryo NED 6-DoF robotic arm

We are working on the Niryo NED 6-DoF robotic arm that the School of Digital Science has recently acquired. The RPi firmware that came with the NED is an older version and is not compatible with the latest version of Niryo Studio, 4.1.0. So, we upgraded the firmware to 4.1.0.
