Choose where you spawn on the map

[Geotree12]

First time contributing to a code base so sorry if it's not too good right now, had to make a couple helper functions from osm_parser.rs public to translate from lng/lat coordinates to minecraft coordinates as well.

New parameter is added
--spawn-point="longitude,latitude"

when this parameter is not specified the spawn point defaults to 0,0

Looks good, but it doesn't pass the checks because of bad formatting, you should execute cargo fmt and push another commit to fix this

got it all fixed up now, clippy was a bit cranky but it should all be good.
