postgis_raster extension not loaded

[matburnham]

flask database init doesn't create extension postgis_raster so raster2pgsql fails:

$ raster2pgsql *.tif -s 4326 -d -M -C -I -F -t 25x25 public.elevation | psql -d ogn
Processing 1/4: 30N000E_20101117_gmted_mea075.tif

Simple fix is to apply create extension postgis_raster manually, but it would be nicer if I didn't have to remember.

Looks like sbrodehl/ogn-python@355158c fixes this.
