Java axis order

see discussion here: mobie/mobie-io#122

@tischi: your suggestion would be to perform the reversal at this level? or just something to be aware of that a level higher will be doing the reversing?

my 2cents: after working a bit on this in mobie-io in the last few days I think it would be best to reverse all the spatial metadata immediately when it's being parsed to match the reversed "zarr-level" spatial metadata, i.e. shape and chunks. This way one can use the same axis order when indexing all the spatial metadata.
(This statement relates to working in imglib2 / n5-java ecosystem, where we have xyz axis order, I don't know if this is true for all java zarr implementations and which one you want to use here).

Hmmm..... that still leaves me wondering which level to apply this at.

I guess I am not quite sure what different levels we have, but without knowing much of the context I would say: "at the earliest point the metadata is parsed in a ome.zarr specific library"

I am also not sure. I think this will become clearer once we have some code.
