Adding download & usher tree build scripts for several non-SARS-CoV-2 viruses.
mpxv has been going for over a year, rsv & dengue for some months now.  fluA is an incomplete work in progress,
complicated by having 8 segments, greater distances, and different subtyping schemes for different segments and even for different types within the segments.
