Updated atom energies for CCSD(T)-F12 jobs

Previous bond energies were calculated using
the F12b method,updated them to now use the F12a energies.

These energies have been provided by Caleb Class
and Beat Buesser.
Add corrections for various model chem in cantherm

All these values are still a work-in-prgress obtained from Beat.
However, the recent updates for cantherm made by Shamel and I are a bit
incomplete without these.

Atomic energy corrections are provided for:
CCSD(T)-F12/cc-pVDZ-F12_H-TZ
CCSD(T)-F12/cc-pVDZ-F12
CCSD(T)-F12/cc-pCVDZ-F12
CCSD(T)-F12/aug-cc-pVDZ
B-CCSD(T)-F12/cc-pVDZ-F12

Bond energy corrections were added for CCSD(T)-F12/cc-pVDZ-F12

Additionally, there were bug fixes and additional unit tests for the
Molepro parser.
Tidy up thermo comments in chemkin files.

-Removed unecessary declaration line '! Thermo Comments:'
-Added 'Thermo library:' label to thermo originating from thermo libraries.
-Removed the NASA fitting to Wilhoit comments because they clutter up the comments
Tidy up kinetics comments in chemkin files.

-Removed unecessary declation of '! Kinetics comments:'
-Fixed labeling of exact rate rule matches (was falsely labeling some kinetics
as estimates when they were actually exact matches)
-Removed extra line with reaction string using original names.  The chemkin
reaction string should be sufficient.
-Removed line commenting on flux pairs (generates clutter and not super useful)

Concern:
- When merging RMG models together, a lot of comments will be duplicated.
This should be fixed later.
