Incremental Loading P2 - dataset_update for changing resources

[alexglasertpx]

Overview
From ticket #341 we now have a new dataset_update function, but this is set up for resources that have not had their entities changed. Need to see what happens at present when have values that get changed and does our current code still work for these instances.

Tasklist

• What possible changes occur in the files?
• Check what happens to the tables if any info regarding the resources is changed [1 if works, might need more depending on what happens]
  • Write tests for changes in tables when resources are changed.
• Could incorporate the state.json file and overwrite incremental loading if any edits made if too complex.
