Updated H_Abstraction TS_training with automated GA geometries

The automated group additive transition state search found
131 transition states. These have been added to TS_training
with the duplicate reactions removed.
Retrained the H_Abstraction TS_groups from the newly added data
Added reverse reactions to the H_Abstraction TS_training

The previous commit added new reactions while ensuring no
duplicates existed in the training data. The reverse reactions
are also H_abstractions and should be included in the training
set, so they have now been added.
Trained the TS_groups with the extra data

Retrained with the same reactions, but with the reverse
reactions added in. A total of 296 (148 unique) non-duplicate
reaction saddle points have now been included in the training set.
