Add Kuwait

closes #2101 and adds Kuwait to the map
@corradio it's up to you to make this zone colored (due to no breakdown but "unknown") or leave it grey but supply the data in the diagramms (like for the JP-zones) ;)

• read electric load from Ministry of Energy & Water (updated several times / hour)

  • load = production due to no imports/exports with neighbour zones

• assign installed capacity to solar, wind, oil and gas

• assign carbon intensity of 595 g/kWh to the unknown mix (based on IEA shares for 2017)

• Note: KW has no significant solar or wind capacity yet, but huge PV+CSP-solar projects are planned for future (GW-range)

SAMPLE OUTPUT:

fetch_production() ->
{'zoneKey': 'KW', 'datetime': datetime.datetime(2019, 11, 24, 12, 6, 49, 945003, tzinfo=tzfile('Asia/Kuwait')), 'production': {'unknown': 6284}, 'source': 'mew.gov.kw'}
