Update README.md to clarify optimization criteria (#374)

* Update README.md to clarify optimization criteria

Unfortunately the dataset was created with an incorrect description that the procedure used the 'GAU_LOOSE' convergence criteria. In fact, the default 'GAU' is used. This PR updates the description adn clarifies for future viewers.

@@ -9,9 +9,10 @@ For each molecule, a set of up to 5 conformers were generated by:
   * generating a set of up to 1000 conformers with a RMS cutoff of 0.5 Å using the OpenEye backend of the OpenFF toolkit
   * applying ELF conformer selection (max 5 conformers) using OpenEye
 
-Each conformer will be converged according to the 'GAU_LOOSE' criteria.
 We only save the results (gradient, wavefunction, etc.) for the final conformation in each optimization trajectory to reduce storage requirements.
 
+In the original submission and in the dataset, we incorrectly described the protocol as using the 'GAU_LOOSE' convergence criteria. However, this dataset was actually optimized with the default 'GAU' criteria.
