feat: experimental navigator for experimental geometry

[andiwand]

first draft of a navigator which can deal with the new geometry, navigation delegates and navigation state

I also added a small unit test that navigates through a box in a box

it also seemed to successfully find all the surfaces in a muon chamber mock up geometry

moved the code into this branch/PR @asalzburger @dimitra97

apparently I forgot to press the submit button again 😄

here are my comments from yesterday

[andiwand]

so I think two things are missing now: the start and the target surface. I think I will add it to stay compatible with the existing navigator and we will need it for the fitters anyway.

the other thing would be to make the unit test actually assert on something

IMO we could merge as is because it is just experimental and it will make prototyping for muons easier

[asalzburger]

Let's move this in & we can refine if needed in a follow-up.

[asalzburger]

@andiwand - ok, let's move this in, such that we can establish first testbeds, if we need refining/updating we will anyway learn this when using the new navigation interface.

[asalzburger]

Great job, by the way!
