 - Created a new FixateError base class for all exceptions raised by fixate to use. It inherits from Exception instead of BaseExcepetion to improve error handling.
 - DSO Driver function 'waveform_values' now returns a single channels x and y data as two separate lists, without re-acquiring the signal. This function should
   now be called after performing signal acquisition.
+- Invert channel and vtime funcitons implemented in the DSO driver.
