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.
