Add missing dependencies which prevent oedialect to work after fresh install

[Bachibouzouk]

I don't know if we should also specify the version of psycopg2 or geoalchemy which should be installed.

On my laptop (linux)
pip install psycopg2
did not work
I had to do
pip install psycopg2-binary

Recently, I did fresh install to test passwordless OEP connection. During the installation, I noticed that even more packages are required. For sucessfuly executing this command

from sqlalchemy import create_engine
import oedialect

OED_STRING_PWLESS = 'postgresql+oedialect://openenergy-platform.org'

engine = create_engine(OED_STRING_PWLESS)
conn = engine.connect()

print(engine.dialect.has_table(conn, 'ego_dp_res_powerplant_reaosm', 'sandbox'))

I needed to install the following packages

• sqlalchemy
• psycopg2
• geoalchemy2
• shapely
• python-dateutil

When updating the requirements, what about the last two of my list?
