Error with coordinates() when zeros after decimal point

Hi, thanks for this library.
An error occurs while retrieving page coordinates 'KAAD-LP'.

```js
wiki().page('KAAD-LP')
    .then(page => page.coordinates())
    .then(console.log);
```
Probably a problem with the coordinate format:
`37/58/57.00|N|120|22|43.00|W`

There are zeros after the decimal point
