The `getGPS()` method in `lib/PHPExif` had a return value of `array|boolean` in the PHPDoc block. The return value should always be a string. `setGPS()` accepts a string, and when the GPS data value is written directly elsewhere in this library, it is also set to a string. This was causing issues during static analysis. I changed the return type in the PHPDoc block to `string|boolean`.
