Include strain and date annotations for sequenced vaccine strains

This commit adds strain and date annotations for 5 vaccine strains that all descend from Edmonston isolate collected in 1954. The Parks et al. paper describes these well. I purposely chose not to include location for these as I wanted the gray dot in the Auspice tree to make these look a bit different than wild-type isolates

This also includes strain, date and location for Edmonston WT strain.
