Show more context samples in downsampled tree, max out 5k sequences #341

It would be great if there were more nearby context samples shown in the downsampled tree. The downsampled tree is very useful when investigating questions like "How many big clusters with S:671S are there in XBB". In that case I'm not interested in everything before XBB, but currently the tree is dominated by samples from before XBB:

The actual part of the tree I'm interested in is this part:

But there are only ~400 sequences. It would be nice if the downsampled tree could pull in more context close to the uploaded sequences so distinct lineages are better differentiated.

Auspice does fine up to 5k sequences, so there's still space in terms of how many sequences can be displayed on the tree.
