Initial addition

@ewels here it is :+1: 

This is WIP repo, so can be merged without a review (for now) :)
But I don't really get what you need it for here? This is to pick up command line options, right? When would anyone specify the UPPMAX id or ordered reads on the command line? I don't think I understand this properly though as it would have to be added as an optional ArgParse as well..
