Enhancement: clean-up

 * removed empty CTOR
 * documented Exception thrown
Enhancement: check return value before we continue

 * check if the file was read
 * throw exception otherwise
Bugfix: check for 'Differences'

 * fixes E_WARNING raised from later foreach ()
 * exit early when no differences are found
 * check false !== to avoid needless loop and errors
Refactor: exit early when condition is not met

 * avoid code wrapped in giant if
 * always throw first to avoid else
Enhancement: add interface so we enforce method getTranslations()

 * also allows for type-hinting in code (see Encoding.php)
Enhancement: documented more parameters
Fix: PHP Catchable fatal error:  Object of class Smalot\PdfParser\Encoding could not be converted to string
