Add example of using q(quat) in the snapshot interpolation example

[ip3ly5]

Snapshot interpolation has been working brilliantly for me when using single number values,
but when I try to use quaternion I get the error "No lerp method "linear" found!".

I think it's an issue with my code but showing how to use quat/deg/rad in the example would go a long way to help others who might also be struggling.

There is an example. Doesn't it work?

Sorry I should've been more clear, I've been using the examples in your link with little success, I could not get them to work. I was thinking that showing its usage in this example project would be very useful.

I have visualized it and it looks like there is a issue with the calculation.

Edit:
I made a typo in the example. Now it works
