Add FRC 2026 game piece detection models

[cobouch]

Description

Added a model for detecting Rebuilt's FUEL game piece for versions of the Orange Pi 5 and the Rubik Pi 3, which lowers the bar for less experienced FRC teams to use object detection on their robots. Also updated the documentation of object detection to reference the new models.

The original model weights were trained by FRC team 2826 and were published on this Chief Delphi thread.

The dataset used for RKNN quantization is the Fuel V3 dataset provided by frcroboraiders on Roboflow Universe.
