cig c961e81ce9 Broken down get_band into two functions to get duplex offset and frame type
- the band is coming from the SI, therefore a function to get the band is not
  necessary
- this solves also the limitations of the get_band algorithm with the NR bands
  overlapping in the NR operating bands table (e.g. band 78 and band 48)
