Create APIs for address risk

[elucherini]

Description

Implementing issue #128. Reopening from #130.

Three APIs with related tests:

• API that, given an address, tells whether it is a soft story
• API that, given an address, tells whether it is in a liquefaction seismic zone
• API that, given an address, tells whether it is in a zone at risk of tsunami

Translating the address obtained through MapBox autocomplete into a geometrical Point could be handled by the frontend (so we keep all MapBox-related stuff in the frontend), so it is currently out of scope.

Also added pre_commit to requirements-dev.txt.

Type of changes

• Bugfix
• Chore
• New Feature

Testing

• I added automated tests
• I think tests are unnecessary

How to test

• Run app

Soft-story

• Go to http://localhost:8000/soft-stories/is-soft-story?lon=-122.446575165&lat=37.766034349 and see that the response is true. This is a coordinate in our soft-story table.
• Go to http://localhost:8000/soft-stories/is-soft-story?lon=0&lat=0 and see that the response is false. This is Null Island, which is not in our table.

Liquefaction

Not required, but oh well.

• Go to http://localhost:8000/liquefaction-zones/is-in-liquefaction-zone?lon=-122.407436&lat=37.779759 and see that the response is true. This is a point at 6th and Howard in a liquefaction zone.
• Go to http://localhost:8000/liquefaction-zones/is-in-liquefaction-zone?lon=0&lat=0 and see that the response is false. This is Null Island. Maybe it is in a liquefaction zone, but it's certainly out of our jurisdiction.

Tsunami

• Go to http://localhost:8000/tsunami-zones/is-in-tsunami-zone?lon=-122.509515&lat=37.759039 and see that the response is true. This is a point in the Outer Sunset in our table.
• Go to http://localhost:8000/tsunami-zones/is-in-tsunami-zone?lon=0&lat=0 and see that the response is false. This is Null Island. Maybe it is at Tsunami risk but it's certainly out of our jurisdiction.

Seismic hazard

• Go to http://localhost:8000/seismic-zones/is-in-seismic-zone?lon=-122.407436&lat=37.779759 and see that the response is true. This is a point at 6th and Howard in a seismic hazard zone.
• Go to http://localhost:8000/seismic-zones/is-in-seismic-zone?lon=0&lat=0 and see that the response is false. This is Null Island. Maybe it is in a seismic zone, but it's certainly out of our jurisdiction.
