Add third viewer: a one-row Linear Genome Overview

[jjti]

Summarize your feature idea. (Why)

This has been our most important request so far. The circular view is great because it gives an overview of the full sequence. However, it's circular, which should only represent plasmids. We would LOVE a similar linear view, similar to what Snapgene does (does really well btw).

This would also largely solve viewing much bigger sequences, such as organisms where scrolling through millions of bp is unfeasible.

Hello @jjtimmons I will see if I can build it myself, can probably PR back after Im done.

Got something preliminary working but still figuring out some bugs with selection and row height.

This is epic, @bugzpodder. I'm a bit swamped with day job for next short bit, but I'd be game to sync and help get this in. Thanks a ton for taking this on
