bugfix: fix frequencies in nr_bandtable

A test with band 79 was not working. It turns out that the computation
of the frequency from the NR-ARFCN was giving a wrong value.

After fixing band 79 as found in this commit, the frequency was correct.

The array nr_bandtable has then been reviewed fully and all the values
that were wrong have been changed. The check of correctness was done
using the website https://www.sqimway.com/nr_band.php
