Change zoom level for NE states/provinces (#1184)
Fixes #1055 

This PR moves Natural Earth zoom 7.7 boundary lines into zoom 4.

> Hi, thank you for PR. In github-actions statistics there is a pretty high size increase in zooms 3, 2, 1, which are using data from zoom 4. Maybe keep your change to move `min_zoom <= 7.7` just for zoom 4, but for zoom 3 add a condition `min_zoom <= 7` (that subsequently the condition bubbles into zoom 2 and 1). What do you think?

I agree that this makes sense, and thank you for pointing it out.  It didn't occur to me that the zoom 1-3 tables were unbounded.  I made the change to pull the `min_zoom` column into the zoom 4 generalized table and filter for `min_zoom< 7`.

With this change, here is Algeria, zoom 3:
