LaserScanAngularBoundsFilterInPlace doesn't handle angle wrap around

[gftabor]

I would like to make a filter remove angles directly behind the lidar. The message is (-3.14,3.14), it would be nice if I could specify (min = 3.0, max =3.28) and it would filter out (-3,-3.14) and (3,3.14).

Also being able to write in degrees optionally would make my config file look a lot cleaner and put the math inside the source code.

Handling wraparound sounds good - if you implement it I'll review the PR. Adding support for degrees is unlikely - radians are the standard across ROS.

@jonbinney I did make a PR for this (#261).

Thanks! I'll take a look at it this week
