Loading RMG's Chemkin output files in ChemkinPro - species name syntax error

[MichalKesl]

Bug Description

I encountered issues when attempting to load RMG's Chemkin output into ChemkinPro. The problems are related to the syntax of species names:

1. Species names starting with numbers:
   Species names like 3-n-dodecyl(100) or 1-C11H23(198) trigger the error:
   "Error...species starts with a number". I resolved this issue by renaming the species but it complained when the name was too long to.

2. Surface mechanism issues:
   In the surface mechanism, the site for adsorption is named, for example, site(3), which conflicts with the species list name SITE. This results in the error:
   "Error...site must precede THERMO data... SITE3."
   I resolved this issue by renaming the site to something like PT(S).
