Move localization functionality from Flotilla to ISAR

[Christdej]

Describe the new feature you would like to see
Flotilla should ideally not have to deal with localization at all, it should be handled by ISAR and the isar-robot specific repositories. This will remove some complexity from Flotilla. This could be combined with removing / restructuring Decks and Area in Flotilla. Need a way of knowing areas are traversable, this might need functionality to find an area based on pose. Might also need to know about the home pose or docking pose (default localization pose), to display where the robot is going (when going home).
