Specify more robust check to detect if the response variable for continous reproduction tasks is in degrees or radians.

We discussed that already, but I still wanted to note it done so that we keep track of this issue. Currently, we simply evaluate if any value of the response variable is larger than 10. An initial step would be to set that limit to 2*pi as this should be the maximum value you can obtain if you wrap to angles from 0 to 360 degrees from one another without using the wrap function. This would be a more principled thershold to start with.

Maybe we can build from there and then think about a more general way to test for the scaling of the response variable. This will likely be also relevant for accumulator models that will require reaction times in seconds instead of milliseconds. So, coming up with a general solution would be great.

just give a warning if abs(response variable) has > 2*pi, but do not transform

add deg2rad and rad2deg functions
