Side slip angle issue

[JBRDLR]

Discussed in #23

Hello,

I have a question about the side slip angle.

As you can see the picture, in the cycle #4, the steer and yaw rate are almost zero but the side slip angle is large value.

I think it is weird, so I wonder your idea for this issue.

Potential reasons for this issue
i) numerical issues when velocity is close to zero
ii) since this is an angle, +pi and -pi represent the same information; so you might see jumps from +pi and -pi (and vice-versa),

This seems to very likely be the issue.

@woojmn: could you provide or check longitudinalVelocity as well?
