Print icd data only when it is really needed

Reduce the impact and visibility of icd calculations by writing
the data to the planner output only in cases where gas switches
involve:

1) ascent
2) helium is used as part of breathing gas
3) gas switch results in an increase in partial pressure of nitrogen.

Coding change:

1) The code for writing the header of the icd table as well as
   the inclusion of the data in the planner output is made
   conditional on the above three requirements. This involves
   moving the code that writes the table header into the
   function that writes an icd data item to buffer.
2) Manipulation of a boolean variable that controls writing
   of the table header to buffer and that also determines
   whether any icd results should be inluded in the planner
   results.
3) Reorganise comments so that there are not multiple tabs between
   the code and the start of a comment.

Correct type and insert braces where important
