re-route main power trace around marker sensor

[micromouseonline]

It is possible to reroute the motor and power traces to be more clear of the sensor slots

Simplest is to swap J2.5 and J2.6. RIGHT_MOTOR_1 can then be routed 'inside', leaving room to place the PWR trace closer to J2 and further from the marker slot.

Perhaps like this:

An altogether neater solution would be swapping the left and right motor outputs so that all the motor drive traces can be well away from the main line sensor slot.

Review this suggestion for future releases. The current side sensor slots work. The side sensors only have to detect the presence of markers so sensor arrays are not necessary for this task. The propsed track routing is however cleaner and should be considered when other board layout changes are being made.
