!! `geopoint` operator

The `geopoint` operator converts separate latitude, longitude and (optionally) altitude numbers into a [[GeoJSON Point Feature]] that can be used with other geospatial primitives.

The coordinates are specified as two or three operands:

```
[geopoint<latitude>,<longitude>,<attitude>]
```

Any operands that cannot be interpreted as a valid number will be interpreted as the value zero.

For example:

```
<$text text={{{ [geopoint[51.751944],[-1.257778]] }}}/>
```

Returns:

```
{"type":"Feature","properties":{},"geometry":{"type":"Point","coordinates":[51.751944,-1.257778,0]}}
```
