CAT_DB process has harcoded CAT subdirectory names

[maxibor]

Description of the bug

In the CAT_DB process, the subdirectories names are hardcoded (to database and taxonomy), which is problematic because the newer versions of the CAT database these directories renames to db and tax. Furthermore, the symlinking of these subdirectories in the process might be posing an issue when running using singularity.

Agree, that mdoule is very old and rather fragile

We should entirely replace CAT modules with official ones, and I think from: https://github.com/MGXlab/CAT_pack

Which looks MUCH better (although not yet on bioconda), as it also describves hwo to make custom databses etc.
