Add Enum support for datatype

@katarinasupe Is this something that the maintainers would be interested in seeing a PR for the release after next?

Hi @james-geiger, this is definitely something that would be great since the support for Enum was added to Memgraph a while ago, and it would be good to follow everything that Memgraph added. So, if you're up for it, feel free to open the PR with the implementation 😄

Would love to see this! Is there a workaround for supporting enums with GQLAlchemy?
