Move dirmult from Suggests to Imports so clusterSize works after a standard
installation. Remove the redundant dependency check and its misleading
Poisson error message.

Add tests for genData() and addColumns() with zero and positive dispersion,
covering integer nonnegative sizes, totals, balance and identifier preservation.

Validation on Windows:

• Installation with mandatory dependencies passed.
• Full R 4.5.2 build/check, including vignettes and manual: clean.
• R 4.6.0 suite: no failures, with dependency build-version warnings.

Linux, macOS, R-devel and remote CI have not been tested.

Fixes #257

Hi @kgoldfeld, a quick follow-up on this fix for the clusterSize() dependency. The CI workflows are awaiting approval. Could you enable them when you have a chance? Happy to address any review feedback.

Thanks!

Yes - I need to get to this - been a bit busy. I'll try for later this week.
