Describe the bug

I am seeing error like this when attempting to us NV12 format

Rerun ERROR: Image buffer has the wrong size. Got 3072000 bytes, expected 4096000

https://ref.rerun.io/docs/cpp/stable/namespacererun_1_1datatypes.html

Upon checking I suspect the image_utils.hpp wrongly code NV12 as 4:2:2 type, where it should be 4:2:0 type which is consistent in docs and rest of Internet.
