BLOCKED: Most big box stores should be visible earlier (z15, z16)

[nvkelso]

Home Depot and Target should be visible earlier than z17 and z16 respectively (both should probably be visible at z15).

This might require vector tile work, but there are area limits in the scene file that could be compounding this.

(The fact that there are 2 Target stores on either side of the interstate here is true but crazy awesome.)

/cc @zerebubuth to investigate if vector tile data source issue(s) need to be filed.

We're missing some types of hardware store, adding them to tiles is covered in:
