Inverts a CASA channel selection string, for example, turning line-free channels into line-full channels. See also countChannels and shiftChannelSelection.

Usage:

tt.invertChannelRanges(invertstring, nchan=0, vis='', spw='', separator=';')

Specify either nchan or a measurement set and spw.

Example:

CASA <4>: tt.invertChannelRanges('4~9',nchan=48)
inverse = '0~3;10~47'                           
  Out[4]: '0~3;10~47'
