Scalar Functions
Compute the [quadkey](https://learn.microsoft.com/en-us/bingmaps/articles/bing-maps-tile-system) for a given lon/lat point at a given level.
Note that the the parameter order is **longitude**, **latitude**.  
`level` has to be between 1 and 23, inclusive.  
The input coordinates will be clamped to the lon/lat bounds of the earth (longitude between -180 and 180, latitude between -85.05112878 and 85.05112878).  
The geometry overload throws an error if the input geometry is not a `POINT`
