📄 Description

This massively reduces the size of the container, by removing things which aren't needed, and not downloading them in the first place.

Required a special case for psycopg2, as libpq-dev isn't included in debian slim.

python:3.9: 332mb compressed, 911mb uncompressed.
python:3.9-slim: 43mb compressed, 122mb uncompressed.

Quite a saving by doing almost nothing.
