Type error when no location is set.

[samhibberd]

If the map field is passed an array with empty string, rather than floats or null values, BaseLocation.php throws a TypeError:

Cannot assign string to property ether\simplemap\models\BaseLocation::$lat of type ?float

Although it won't validate shouldnt the Map field be able to handle a value like this:

Bit of normalization in the map fields normalizeValue() method should cover it, happy to submit a RR if easier?

Any thoughts on this one?
