Lower AprilTagDetector's maxLineFitMSE

[Gold856]

Description

Fixes #1817. Based on AprilRobotics/apriltag#375 (comment), I lowered it and light testing seems to indicate that this doesn't really impact range, but it does prevent cutoff tags from being detected. This value could be tuned lower to reduce bad detections even more, or higher to reduce false negatives, but this seems to be a good starting point.
