Reduce nwbins in UKCA_ABDULRAZZAK_GHAN

  • Background: in the process of adding OpenMP to UKCA_ACTIVATE (see UM ticket 3506, I found that 90+% of the time in UKCA_ACTIVATE can be attributed to one DO loop in UKCA_ABDULRAZZAK_GHAN. The outer DO loop for this is over NWBINS, which is used to calculate an area under a graph. Currently, NWBINS=20.
