[Module update] Radiff2 new features

[TcM1911]

• Add a check for div 0
• Use last search if --samples or --all is not used.
• Add feature for "cluster" table. It compares the similarity of the functions in sample x to sample y and the functions in sample y to sample x. The output is printed in a table.
• The table can be written to a csv file at the absolute path by using the --export flag.
