Advanced Parking AI improvement suggestion

[Jcpo23]

Hi ! This is my first contribution.

Advanced Parking AI adds a lot of realism but combined with high density residential lots and European city design it's most of the time a nightmare. IRL high density residential often comes with underground parking. I manually place them with anarchy under zoned buildings but there might be another option :

• Is it possible to add exceptions to the pocket car restriction ?
• When Cims are looking for a parking spot to their high density residence ?
  (Or any other option according with the player experience : this would be a setting in the options.)
• Enabled with the in-game policy tab so it can be a district-only permission ?

thanks a lot for your works !
