Initial addition

@ewels here it is :+1: 

This is WIP repo, so can be merged without a review (for now) :)
Also - when we run this report type in a piper directory, we should be able to get this information from the filesystem.. It'll be quicker to not have to specify this on the command line if we're going there anyway to generate the IGN sample reports or are being executed by the pipeline.

Could we _try_ to scrape this information from the XML file in `common.project_summary` and fail silently if we can't find the information, and then this can just over-write that information if we have it on the command line?
