Refactor incoming

[midgen]

Just an FYI here, I have a fairly big refactor of the plugin in development at the moment. The main effort is to decouple the navigation data itself from the ASVONVolume actor, so the data and config is more neatly encapsulated and I can start building out some automated testing.

I've also got some ML projects on the side which I want to use it for and I need the data to be in a form more easy to run simulations on.

There won't be any major changes to the configuration, but the serialization of ASVONVolume has changed so you'll likely need to delete and recreate any saved volumes, although there should be some way to elegantly deal with the serialization mismatch, is does just crash at the moment!

I'll be publishing this on the https://github.com/midgen/uesvon/tree/V2 branch initially

I plan in implementing some decent path optimisations and smooth path follower component options.
