Issue Description

I noticed that for the L515 depth intrinsics the model and the coefficients seem buggy. The model is a random integer (eg. 1740629008 or -1669339168) that doesn't match the Distortion enum. The coefficients also change every time I run the application and their values look a bit fishy to me:

Looking at the code it seems the issue is that the values are simply not set. If the depth sensor of the L515 doesn't have distortion the model should be None aka 0, right? Initializing the distortion coefficients to 0 would also be a nice touch.
