[Feature]: Preserve HDF5 dataset filter settings on export to Zarr if possible

[oruebel]

What would you like to see added to HDMF-ZARR?

On export infer HDF5 dataset filter and chunking settings from the data such that they can be preserved in Zar on export.

Is your feature request related to a problem?

To compare HDF5 and Zarr the files should use matching settings. As such it would be convenient to be able to convert from HDF5 to Zarr and preserve dataset settings if possible.

Also, when converting from HDF5 to Zarr, it is desirable to preserve settings to avoid growth of data due to lack of compression and preserve chunking options.

What solution would you like?

• Kerchunk has https://github.com/fsspec/kerchunk/blob/617d9ce06b9d02375ec0e5584541fcfa9e99014a/kerchunk/hdf.py#L181 to infer Zarr filters from HDF5

Do you have any interest in helping implement the feature?

Yes.
