Return distance when sorting by _geo_distance

[Kayrim]

would be awesome if we could include the distance value with the search result.

I know this can be done with SQL but would be great if we could add it to the result.

Similar to how we add score with $search->trackScores(true)

Something like $search->trackDistance(true) ? maybe

Will possibly add it locally, if it works would you like a PR?

Yes, we'd like a PR about it. Thanks!
