Higher taxonomic piecharts like Genus, Family because we imply but dont deliver

[mkoo]

Right now, I think when specificepithet = null then a Genus-only piechart is generated.
EX. https://amphibiandisease.org/dashboard/?id=Rana+undefined

That is not an accurate representation of the data as it implies it's all species within Rana that is displayed which is a reasonable expectation. We should either remove from the species list the piechart entries where specificepithet = null.

Instead we should have a new piecharts where we display data based on higher taxonomic classifications like Genus, Family, Order (yes, probably should be a new issue)
