[Feature]: Export dtypes

[mavaylon1]

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

Currently when exporting from different backends, i.e HDF5 to Zarr, we run into a dtype conversion from "uint32" to "int32". This should not happen and should remain "uint32".

To reproduce, run the plot_convet_nwb_hdf5.py tutorial.

Is your feature request related to a problem?

No response

What solution would you like?

Explore either the zarr backend or the convert_dtype method in object_mapper.py in HDMF.

Do you have any interest in helping implement the feature?

Yes.
