Add support for outdoor navigation

[crdelsey]

Feature description

The navigation stack should support navigating in an outdoor environment. This includes features such as:

• Taking the unevenness of terrain into account in planning.
• Taking the unevenness of terrain into account when processing sensor data
• Detecting whether uneven terrain is navigable or not.
• Handling very large maps
• Localizing when the nearest features are very far away
• Fusing AMCL localization with GPS localization

The AMCL and prior lines are probably removable, if you're really outdoor on uneven terrian, AMCL and 2D mapping in general are poor examples. I think its reasonable to assume positioning is on the user unless we want to get into the 3D slam and localization game in this metapackage
