Update to v1.34.0 - Ertl Scaffold Keys

We have today added another update to our community contribution. This contribution adds a single cheminformatics node adding our implementation of Peter Ertl’s ‘Scaffold Keys’ (the references for this are available in the Node Description). In addition to providing the individual key counts, the node can optionally also output SVG visualisations of the atoms for the key, as shown below

As always, please do get in touch if you spot any problems or have any suggestions for improvements to the node,
