Reads hdf5 files according to OPERA conventions
Please refer to the OPERA data model documentation [B1] in order to understand how an hdf5 file is organized that conforms to the OPERA ODIM_H5 conventions.
In contrast to other file readers under
wradlib.io, this function will not return a two item tuple with (data, metadata). Instead, this function returns ONE dictionary that contains all the file contents - both data and metadata. The keys of the output dictionary conform to the Group/Subgroup directory branches of the original file. If the end member of a branch (or path) is “data”, then the corresponding item of output dictionary is a numpy array with actual data.
Any other end member (either how, where, and what) will contain the meta information applying to the corresponding level of the file hierarchy.
