kleborate is failing tests on s390x

[nileshpatra]

Hi,

First off, Thanks for your work on Kleborate!
Actually, Kleborate does not pass its testsuite anymore on s390x and any other Big Endian architectures. The version 2.0.1 worked just fine, but something changed after that and both 2.0.4 and 2.1.0 do not work.

It has a few tests failing, owing to this symptom. Most of it is similar to:

======================================================================
FAIL: test_res_01 (test.test_res_alleles.TestResAlleles)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/<<PKGBUILDDIR>>/.pybuild/cpython3_3.9/build/test/test_res_alleles.py", line 41, in test_res_01
    self.assertEqual(results['Bla_acquired'], 'ABC-1')
AssertionError: '-' != 'ABC-1'
- -
+ ABC-1


======================================================================
FAIL: test_res_02 (test.test_res_alleles.TestResAlleles)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/<<PKGBUILDDIR>>/.pybuild/cpython3_3.9/build/test/test_res_alleles.py", line 49, in test_res_02
    self.assertEqual(results['Bla_acquired'], 'ABC-2')
AssertionError: '-' != 'ABC-2'
- -
+ ABC-2
