filter evictions_blockgroups to just data inside metro limit.

The evictions_blockgroups dataset has the whole state of oregon. I will need either a materialized view or you could just delete the rows from the table that are not in scope. There are 44k rows but only 16k in scope

```select * from evictions_blockgroups
join scope on ST_intersects (evictions_blockgroups.geom, scope.geom)```
