MOB-typer in multi mode does not respect primary cluster mash distance?

[schorlton-bugseq]

Thanks for all of your work on this tool! As per title, I think this comes down to:

In single mode, there is logic to handle mash distance > primary_cluster_dist:
https://github.com/phac-nml/mob-suite/blob/3.1.9/mob_suite/mob_typer.py#L502-L507

I couldn't find similar logic in multi mode (but let me know if I'm missing something!):
https://github.com/phac-nml/mob-suite/blob/3.1.9/mob_suite/mob_typer.py#L436

This leads to MOB-typer clusters with mash distance to nearest neighbour of 1, even when settings left at defaults.

I don't have capacity to fix soon but thought I could at least document as a first step. Thanks again!
