RdRp Explorer - Geo tab - Report "Collection Time" in timeline

Right now we're displaying "SRA dataset released online" as our main "measurement" of time, which is the easiest and a ballpark of "how new" the dataset is.

From a virus-evolution perspective, it would be far better if we could go one level deeper into the meta-data and show the "Collection Dates" (where available of course). This would make for asking very cool queries like "Show me all OC43 sequences sampled before 1995", and bam you end up at something like this sequence from Nashville in 1990, and it's a point right there on the map.
