* feat: return two lists for diffexp (#2221)

* sp

* split out derive sort order, tests passing

* sp

* return diff exp results in two lists

* update

* copy implementation over to desktop

* add tests for two lists

* small fixes to complete backend implementation

* accept new diffexp response

* map diff exp response to genesets

* delete )

* name diffexp genesets with population names

* take constants out of state and allow width prop to override

* shorten mini-histo properly truncate and resize depending on expansion

* prepend new genesets

* rename data within diffexp action
