feat: bug fixes and improvements for migration

[Aclrian]

Closes #1259.

Summary of Changes

Some Improvements to the migrate command:

• include documentation similarity to similarity between two functions
• include function similarity and documentation similarity to similarity between two classes
  • add hash function to Function and FunctionDocumentation
• handle duplicated annotations
  • mark annotations with same type and target as unsure and generate a comment where they differ
• improved output for migration by not printing each line separately
• fix detection of global function in StrictDiffer
• fix weighted levenshtein distance: now higher level changes should have increased costs

Testing Instructions

run test_base_differ.py and test_mapping.py

Feel free to merge this in when it's done. It should now work again as expected.
