gembase format is ESCO.0421.00001.prt for filenames and ESCO.0421.00001.00001i_0001 for protein names
gembase complete genomes format is ESCO.0421.00001.C001.prt nd EXCO.0421.00001.C001_0001 for protein names

-> now, genome names can contain a '.' (but still no '_')

before, it was always the case. Now, there is an option to give a subset of genomes. In all module, give no subset, still run on all genomes

- save family number as int and not str
- raise error if no family found

Before, we used a pool of size 1 to run mmseqs_clust inside, and showed a progress bar in the main thread.
Now, run_mmseqs_clust runs in the main thread, and a progressbar is running in a separate thread, that is stoped when mmseqs_clust has finished.
