Enable to load pyramids #9

Open felixcremer opened 1 year ago

felixcremer commented 1 year ago

We should also be able to load pyramids that we either precomputed with pyramid schemes or that are available in for example a geotiff file. This is linked to #6

Geotiff pyramids will be read when #20 is finished. For zarr pyramids we have to follow the geozarr extension.

This currently works following the zarr multi scale setup described here https://forum.image.sc/t/multiscale-arrays-v0-1/37930 We are currently not using the metadata neither for reading nor writing the data. We assume that the levels are in the original zarr folder and have integers as subpath according to the respective level. We should read the metadata if available to see, whether a file has pyramids available.
