Literacy tweaks

[BrknRobot]

Global starting literacy is decreased.

• This roughly reflects that literacy encompasses a number of skills in Vic3 including reading, writing, comprehension, and numeracy, and many historic literacy estimates are based on the simple ability to sign a document, or scripture memorization, so it's okay for our starting literacy to be below these estimates

Education systems slightly rebalanced

• private schools are nerfed a bit as education access from wealth is very strong. Public and private schools will reach 100% education access at the same wealth level now
• religious schools adjusted to have educational tradeoffs with public education. Religious schools will provide less overall education, and less equitable education, but do it more BUR efficiently than public schools.

Compulsory primary school buffs existing education institutions

• Rather than providing a flat boost to education access, it increases the effects of the education institution

Market access price impact is reduced by illiteracy

• This reflects the wider economic effects of an educated populous, beyond job qualifications

Slaves no longer receive education access from schools

Qualification growth is tweaked

• In particular, pops which don't meet the mimimum requirements will see qualifications decay for every job type, and qualifications will decay more strongly. This should be particularly pronounced for wealth based qualifications
• Pop types described as "any pop can become" actually have baseline levels of qualification growth (necessary since starting literacy has been reduced)
• Instances of peasants becoming capitalists should be greatly reduced. Peasents will have a difficult time meeting the literacy requirements for most job types without investing in education access. This should increase the importance of the qualifications pipeline

Most pop types have some level of inherent education access

• This reflects that a significant driver of increased literacy rates was what people needed in their every day lives, rather than due to seeking higher qualifications. Even labourers get minimal education access, reflecting their need to sign employment contracts, or track paychecks

Urbanization provides education access

• This reflects that books and educational institutions are more available in urban centers and highly populated areas

Mid to late game literacy rates may be higher than vanilla with these changes and may need to be adjusted downward if 100% literacy is too easy to attain
