 Optimization on frequencies translation by rearranging compute steps implemented as proposed by alalons.
 
-Alalons (have I thanked you already?!) proposed an speed optimized arctan function. Performance gain is notable (factor ~2) but could reduce sensitivity slightly on receiving C1 mode datagrams. A speed optimized arctan version can be activated by "-a" in the program options.
