Additional Notes

• Replaced the FEATURE literal type with a Feature enum for better type safety and readability. (src/recordlinker/models/pii.py)
• Separated matchers into two files based on the signature it was using (old schema vs new schema) (src/recordlinker/linkage/matchers.py and src/recordlinker/linking/matchers.py)
• Changed FEATURE_COMPARE_FUNC and MATCH_RULE_FUNC to use floats instead of booleans for more granular matching. (src/recordlinker/linking/matchers.py)
• Added caching to the Patient model for generating its record. (src/recordlinker/models/mpi.py)
