Both tests do not work for me. It seems that the test folders/files are
missing?
And also:
- the `catar_data` folder does not exist, the tests need to create it
(and delete afterwords)
- the `pxar_split_archive_test` test does not correctly clean up
afterwards and leaves the two ppxar and mpxar files in the `tests`
folder.
