Add traversability layer name to python bindings

[GoldenZephyr]

this is another traversability place binding problem that had been left behind in ROS1

[GoldenZephyr]

can you remind be the workflow for merging to main vs. develop?

[nathanhhughes]

LGTM!

@GoldenZephyr basically what you've done so far is the easiest. Once this is merged, you or I can go and fast-forward merge develop locally to be even with main (the other way, PRing into develop also works but I can't remember if you can push to main or not). I think it'll be easier though once #73 and #76 get merged to develop and then the two branches won't be even

@nathanhhughes Another traversability place Python fix that I thought I would stick in here

[GoldenZephyr]

@nathanhhughes At some point could you take a quick look at why the tests are unhappy with how I put in the TraversabilityState bindings? The unit tests fail because of the TraversabilityState binding but I have no idea why

[nathanhhughes]

@GoldenZephyr you already ported that one earlier: e1bb5ad

[GoldenZephyr]

@nathanhhughes fixed, although I think I need you to reapprove
