Bug#974181: python3-sasview: tests fail with h5py 3.1

[Drew Parsons]

Package: python3-sasview
Version: 5.0.3-1+b1
Severity: normal

sasview tests fail with python3-h5py 3.1.0-1exp1 from experimental.

The format of sasview's .h5 test file seems to be inconsistent with
respect to utf-8 encoding.

e.g. error message for cansas_reader_hdf5.test_real_data is
>       raise NoKnownLoaderException(
            "Generic readers failed to load %s" % path)
E       sas.sascalc.dataloader.loader_exceptions.NoKnownLoaderException: Generic readers failed to load /tmp/autopkgtest-lxc.nojro145/downtmp/autopkgtest_tmp/test/sasdataloader/test/test_data/simpleexamplefile.h5
