Subject: Issue #4: Studiennummer und Erkennung des Studientyps hinzugefügt

Der Studientyp wird anhand der Studiennummer erkannt

* `NCT`: Beginnt mit `NCT` (Groß-/Kleinschreibung ignioriert)
* `EUDRA_CT`: Entspricht: `YYYY-NNNNNN-CC`, dabei aufgeteilt in
  (Jahres-)Zahl, sechstelliger sequenzieller Nummer und zweistelliger Prüfziffer
* `UNKNOWN`: Keine Studiennummer angegeben oder entspricht keinem bekannten Schema
