selecting on circular viewer will scroll linear viewer

When you mousedown on circular viewer to make a selection, the linear viewer will automatically scroll to this position using centralIndex.

I did not add a scroll during mouseMove (dragging selection) because the UI would seem very busy with the scrolling.

The package.json changes are for codesandbox, so you can just do: https://githubbox.com/<user>/seqviz/tree/central_index to get a fully working link

Looks good to me. I think there might be folks that would prefer linear to stay where it was -- when selecting on circular -- but imagine they'll be outnumbered by folks that prefer this change. And adding a bunch of props to configure that is outside the scope of this PR

I see, before I was not sure if its an oversight or intentional. your call, I don't really need this feature :)

One question/nit about the new dev commands. Reason being that start is already pretty much dev (for me at least)

So I think there are two things if we want to merge this into one command: In codesandbox, it will look for and run dev script, and if non-exist it will run start script, so my current approach works. However if we do only keeping one script:

• in codesandbox we cannot call open https://localhost:3010, so the only way to keep it a single start script is we remove this. That means locally you will not get the browser to open automatically when you run npm start, which might or not be fine in exchange for keeping only one script. So in short:

• if you want to keep only the start script, then we need to remove the open command in order for codesandbox to work properly, or else add a new codesandbox config

• or keep both dev/start as is

Gotchu, I wasn't aware that this was how it works. I'm totally game w/ the new commands in that case
