Investigate DataTree type from DimensionalData.jl as a potential reader backend #139

[felixcremer]

compare structure of EOPF data and compatibility with DimensionalData implementation

[rafaqz]

Yeah, look forward to seeing this.

I'm going to write Rasters.jl RasterTree readers soon, but maybe we can move those somewhere shared

[felixcremer]

I am happy to use also RasterTree from Rasters. I don't think we would need necessarily YAXArrays here.

[rafaqz]

Yeah, I'm just thinking in future if Rasters should have all the file loading stuff, or be more of a raster algorithms on DimArrays packge

[felixcremer]

I had to switch to using YAXArrays for the leaves of the DimTree for now, because there has been some issues with handling the Time information for the sentinel-1 data.
Using DimTree works and I will rather keep track of more finegrained issues.
