Update for Belgian POPs

[halcyon-gh]

Work in progress on solving #65. Highlights:

Pop counts extrapolated from primary sources (Belgian census data of 1846 and 1856)
Moved Wallonia state capital to Liege (larger and more diverse city, better place to combine small pops).

Remaining issues:

Working from primary sources results in several very small pop groups which seem to disappear in game. It would make sense to merge some of them. Any suggestions on smallest practical pop sizes and which jobs to preferentially assign small cultural groups so they don't assimilate immediately?
Many craftsmen were added so I will also add factories to avoid too many unemployed.

Hi @halcyon-gh. Here are some suggestions

• Remove/change all aristocrat pops from provinces which aren't state capitals, as these pops aren't supposed to be in such provinces . In this case only Brussels, Leige, Luxembourg and Limburg should have aristocrat pops.
• Remove/change all non-accepted bureaucrats as they assimilate pretty quickly unless the non-accepted pops constitute a majority or a significant minority in a province.
• Very small non-accepted pops get assimilated either immediately or very quickly so you should avoid adding them. I try to avoid adding pop types with fewer than 100 pops. However as you said you can merge them. For example you can take all the French pops from all the provinces and put them into a single province, let's say Brussels.
• If some pops are still very small, it's a good idea to change the pop types with the fewer pops, which usually are officers, aristocrats, clerks and capitalists, to the pop types with the most pops like farmers, soldiers or artisans.

Thanks for the suggestions @Libeccio-DD. The updated list now has at most pops from 2 cultures in regular provinces, and 4 in the capital provinces. Minority pops are restricted to be artisans, craftsmen, or farmers/laborers, except in the capital where they are intellectuals, clerks, artisans, or craftsmen to represent minority pops in an urban environment. I left the aristocrats in the individual provinces because this is also the case in the base game.

I also realized that there are already plenty of factory jobs for all clerks and craftsmen, so no need to add any. Next step is to have a look at RGOs and industry, but I will submit a different PR for that.

If anyone is interested, I got all data from these sources:
Census of Belgium, 1846:
Statistique de la Belgique: Population (1846),
Statistique de la Belgique: Industrie (1846)
Census of Belgium, 1856:
Statistique de la Belgique: Population (1856)

If you play as Belgium and check the provinces you'll see that all aristocrat pops in normal provinces are automatically moved to a state capital.

Updated population of Luxembourg, based on Statistiques Historiques 1839-1989 and armee.lu.

And finally an update for Eupen-Malmedy. Part of Prussia in 1836, but later transferred to Belgium after WW1. Population was interpolated based on the 1825 Aachen census and the 1849 Prussian census, assuming a constant yearly growth factor.

The distribution between north_german and walloon pops was set by assuming all pops in Malmedy, Weismes, and Bellevaux were walloon, and all others were north_german.

Soldier pops were changed from north_german to walloon since 148 out of 161 soldiers in the 1849 census were from the town of Malmedy. The proportion of other pop types was not changed.
