Enable full FOV output from RGB camera

[VanDavv]

With this PR, the preview from the RGB camera is adjusted to meet the full FOV aspect ratio

Yes this is a lot nicer!

So a quick question - the 1920x1080 (I presume that's the sensor config) is cropped out of the aspect ratio of the full image sensor, is that right?

[Luxonis-Brandon]

But it looks like the spatial location calculator is being used wrong. Look at the location of the TV monitor in the background.

I think the wrong locations are being used between depth and RGB.

Here's a video showing it:

Yes, I saw that too, and I think that's due to the lack of RGB-Depth alignment. Started to work on it here but had some issues

[Luxonis-Brandon]

So I think it's different than RGB depth alignment. As w/out this PR the distances seem correct.

Here's a video of what's in main for example:

Full FOV preview was enabled in #433 due to performance requirements
