tiger-lib 1.18.0

Library used by the tools ck3-tiger, vic3-tiger, and imperator-tiger. This library holds the bulk of the code for them. It can be built either for ck3-tiger with the feature ck3, or for vic3-tiger with the feature vic3, or for imperator-tiger with the feature imperator, but not both at the same time.
