- Renamed attributes for better clarity (e.g., inserted to insertions, start to �uthored_at)
- Removed redundant attributes like ile_paths
- Consolidated datetime attributes (start and end to �uthored_at and committed_at)
- Standardized uid attribute to id across various domain classes

- Improved naming clarity: Renamed command groups from gitlab_cli to gitlab2prov and github_cli to github2prov.
- Refined config validation and loading: Split invoke_command_line_from_config to separate functions for loading and validation (load_and_validate_config) and command execution (execute_command_from_config).
- Introduced clear separation between loading and validation of config to provide clearer error messages.
- Replaced --verbose option with --explain for statistics command for better understanding of its purpose.
- Minor cleanups: Removed unnecessary whitespace and lines.

- Introduced post-initialization method __post_init__ to parse the URL upon object creation, thus reducing repetitive calls to urlsplit.
- Simplified slug property logic by utilizing the parsed URL path directly, ensuring clearer and more concise code.
- Removed individual properties for
etloc and scheme in favor of the parsed attributes from __post_init__.
- Streamlined the clone_url method by removing redundant parameters and leveraging a dictionary lookup for platform-specific URLs.
- Adapted child classes GitlabProjectUrl and GithubProjectUrl to match the streamlined method signature.

- Add 'deletions', 'insertions', 'lines', and 'files_changed' attributes to 'extract_commits'.
- Rename 'start' to 'authored_at' and 'end' to 'committed_at' in 'extract_commits'.
- Add 'insertions', 'deletions', 'lines', and 'score' attributes to 'FileRevision' in 'extract_revisions'.
- Correct typo in comment from 'remeber' to 'remember' in 'extract_revisions'.

- Introduced a ilter_valid method to filter annotations without �nnotator or start values.
- Modified parse method to use ilter_valid after sorting annotations.
- Changed property name uid to id in methods: parse_commit_comment, parse_commit_status, parse_award_reaction, parse_issue_comment, and parse_issue_event.
- Removed extraneous whitespace after parse_award_reaction method.

- Replaced uid with id in the methods for parsing notes, comments, awards, and labels.

- Improved docstrings for clarity in various methods.
- Updated error handling in the 
ead_provenance_file method to handle file not found exceptions.
- Refactored the deserialize_string method to provide better feedback on deserialization failures.
- Modified the file write mode in write_provenance_file based on the overwrite parameter.
- Enhanced ASCII table formatting in ormat_stats_as_ascii_table.
- Introduced new methods for pseudonymization:
  - generate_pseudonym
  - pseudonymize_agent
  - pseudonymize_relation
  - Overhauled existing pseudonymize method for better clarity and efficiency.
