Bug#1108343: apt-xapian-index: axi-cache does not specify python3-six dependency

[Thomas Schneider <qsx@chaotikum.eu>]

Package: apt-xapian-index
Version: 0.53
Severity: important
File: /usr/bin/axi-cache

Dear Maintainer,

axi-cache(1) from apt-xapian-index requires python3-six, however it does
not depend on it.  Unless python3-six is installed manually or as
dependency of another installed package, running axi-cache fails:

```
root@1d2b1e719507:/# axi-cache -h
Traceback (most recent call last):
  File "/usr/bin/axi-cache", line 32, in <module>
    from six import StringIO
ModuleNotFoundError: No module named 'six'
```

Thanks,
Thomas Schneider
