Description: Describe your changes here...

Added new option, freqref, to NRO filler. Posible values are:
1) 'rest' to import frequency in REST frame, which results in an exactly
same frequency label as NEWSTAR, and 2) 'vref' to import frequency
in the frame that source velocity refers, which results in the same
velocity label as NEWSTAR. The option must be given to scantable
constructor.
