feat(parser): Build OPENELECTRICITY parser

[VIKTORVAV99]

Description

This is very much a work in progress PR but it adds the basics of a new parser for open electricity.

Its still missing exchange flows and it's missing solar rooftop power. But the core is there and it's working as intended.

There is a python package we could use to try and simplify this: https://github.com/opennem/openelectricity-python but I's still in beta so IDK if we should do that yet.

Double check

• I have tested my parser changes locally with poetry run test_parser "zone_key"
• I have run pnpx prettier@2 --write . and poetry run format in the top level directory to format my changes.

checked up on this while doing #8289
AFAIK:

• python client is not yet stable
• https://api.openelectricity.org.au/v4/data/network/ would work for production data but not for imports/exports
• they do accept "imports", "exports", "interconnectors" as valid "fueltech" but the api calls don't return any data
• we can filter for zones in the api to get a cleaner response
