Description
Currently the data is not loaded so that the correct missing value is used.
We should switch the data loading to using Rasters instead of YAXArrays.

Research direction
Start by locating the TIFF pyramid data-loading path and the code that creates coarser levels. Compare the current YAXArrays loading with the intended Rasters-based loading, then verify that missing values are preserved correctly at coarser levels. Done means TIFF pyramids use Rasters for loading and apply the correct missing value.
