Province modifiers fixes

Assumes https://github.com/gbasood/ShatteredEuropeEU4/pull/3 happened.

It updates the map (based on older version of EU4) by adding province modifiers - estuaries, COTs, and religious centers, and removing obsolete `cot = yes/no`.

There's also some other weird differences, like trade good changes, buildings etc., I didn't incorporate any of those into this pull request. I have hard time distinguishing what's intentional for the scenario, and what's just early EU4 patches stuff.
