Made `HeightVector` numerically safe; while `Vector` remains numerically unsafe (i.e. it can divide by 0, NaN, Inf, etc).
When HeightVector runs into a problem, it just re-randomizes itself. Since the algorithm converges relatively quickly, this seems to work fine.
Also fixed a bug so that now height will always start as a positive number (and stay that way, else get re-randomized).
Added safety to `NetworkCoordinate` which now checks that its error didn’t pull a `HeightVector` into a negative height; in which case it also re-randomizes.
Clarified the `random` construction, tweaked the DEFAULT_ERROR constant, and updated tests accordingly.

- public NetworkCoordinate so it’s easer to just `use vivaldi_nc::NetworkCoordinate`
- add module level docs and examples in lib.rs
- cleanup README

Adds serialization/deserialization support via serde and serde_with.
Also:
- remove `license-file` in Cargo.toml (superfluous)
- update README with Getting Started section
- add `serde` and `serde_with` dependencies to README
- add tests to `HeightVector`
- tweak assertion in `NetworkCoordinate`
- refactor `Vector` to be a struct witn an `inner` instead of a tuple struct so that we can use `serde_as` (from `serde_with`) to help us derive SerDe implementations for the const generic sized array
- moved trait requirements (which are getting long) into where clauses
