Reimplement spin kick watcher

[kylestach]

Description

Port the spin kick watcher to the new ROS referee. This was not possible as of #1554 as it requires the vision filter, but as soon as #1555 is merged this can be worked on.

This enables opponent restarts.

Requirements

• Properly handle opponent restarts

Design

1. When we enter the "ready" state, capture the current ball position
2. Switch to the "playing" state once the ball moves by a certain amount

An equivalent implementation can be seen in the old code.
