Integrate Puppet Commanders

This adds a simple decision to acquire the commanders of integrated puppets, allowing you to keep them in the game should you choose to annex a puppet, just like how china can integrate the commanders and armies of the warlords, or how Britain acquires French commanders in the event of the Franco-British Union.

Upon integration you get a minor org penalty (-5%) for 180 days to reflect difficulties for new commanders to adapt to a new system, and to overcome possible language barriers integration may present. After 180 days, you can integrate a puppets commanders again, acquiring commanders newly recruited by your puppets

As well as recruiting puppet commanders via decision, a one-time event fires if you integrate a puppet whose commanders you have not integrated, allowing you to get them last-minute. if you turn them down however, they will not re-appear unless their home nation is released once more as a puppet.

Works with any combination of puppet/master country, and should be compatibile with any other mods that do not change the vanilla autonomy states. To ensure the decisions are not overwritten by other overhaul mods, please put this mod towards the end of your load order.
