split large workflows into independent workflows if possible

fireworks seems to have trouble in the thousands of TSs range due to the need to acquire lock for all the fireworks running at once
splitting it into independent workflows (when running adsorbates/TSs separately they are each independent) makes the lock separate
to each adsorbate/TS avoiding this issue.
