Complete instrument refactor (except Tektronix)

+The SignalHound, SRS, Stahl, Weinschel and Yokogawa drivers shipping with QCoDeS
+have been updated to ensure all Parameters are set as static
+attributes that are documented and can be type checked. The docs for the same drivers have been
+updated to not document inherited members. This makes the documentation significantly more readable
+as it focuses on specific members for a given instrument. The documentation now also links superclasses.
+Please consult these for inherited members.
