Neo4j >= 4 compatibility (shortestonly and dijkstra-cypher algorithms only)

[aas-n]

Hi,

This should allow to use aclpwn.py with neo4j >= 4.0 and python >= 3 with algorithms shortestonly and dijkstra-cypher.

• shortestonly and dijkstra-cypher were broken because of syntax changes since neo4j v4.
• dijkstra-cypher was partly broken because Graph Algorithms Library was deprecated by GDS.
• Default algorithm (dijkstra) STILL need to be re-implemented since REST API was removed from neo4j v4.

This needs to be double checked. However, it should fix #4 and fix #6. Hope it helps.

Does anyone know the fix to this?
