Move scale bar when zooming

[jywarren]

Currently, dragging the scale bar zooms the map, but not the inverse -- zooming the map should automatically move the scale bar too. We'd love help implementing this!

Here's the slider code:

We could wire it up to change the scale bar on the map's zoom event:

This has been marked as a good candidate for becoming a first-timers-only issue like these, meaning that it's simple, self-contained, and with some extra formatting, could be a great entry point for a new contributor. If you're familiar enough with this code, please consider reformatting or reposting it as a first-timers-only issue, and then ping @publiclab/reviewers to get it labelled. Or, if this is not your first time, try to solve it yourself!
