Inherit defect related triples when operations are performed on the structure

[srmnitc]

will close #158

• generalise extract triples
• stop extract triples at derived samples
• add a new function to create graph from triples
• modify the get_sample function to work with new setup
• add function to create new IDs for URIRefs in the extracted graph
• add function to delete the extracted triples (could be used for removing a sample) (will do in new PR)
• add copy_defects which copy defect triples to a new structure
• use this function in workflow.py
• use this function for all modify methods
