Mars PCM:
Code cleanup concerning chemistry. Turn chimiedata.h into module
chemistrydata.F90 and integrate read_phototable.F in it.
Also fix an OpenMP issue with read_phototable; different OpenMP threads
should not simultaneously open/read a file. Let the master do the job
and then broadcast the result to all cores.
While at it, also turned nltecool.F and nlte_tcool.F into modules.
