/**
 * Convert longitude and latitude to x,y,z coordinates based on a given radius. The options (last parameter) are optional.
 *
 * @example
 * Basic usage
 *```js
 * const coords = geoTo3D(-73.5674, 45.5019, 1, { decimals: 2})
 * // returns  { x: -0.67, y: 0.71, z: 0.2 }
 * ```
 * You can pass { toArray: true } to return an array instead of an object.
 *
 * @param lon
 * @param lat
 * @param radius
 * @param options
 * @param options.decimals - The number of decimal places to keep in the result
 * @param options.toArray - Return an array instead of an object
