- Replace flake8 linting with Black's --check option

This change enhances the CI pipeline by introducing code formatting checks,
ensuring consistent code style across the project.

- Apply consistent formatting to setup.py, cli.py, usb_handle.py, and test_usb_handle.py
- Improve code readability by breaking long lines and adjusting indentation
- Remove unnecessary blank lines and add spacing where needed
- Standardize string quotes (use double quotes consistently)
- Adjust import order in some files

This commit improves code consistency and adheres to PEP 8 style guidelines,
making the codebase more maintainable and easier to read.

* feat(usb_handle): enhance status logging and timing information

- Add start and finish timestamps to status output
- Include total script execution time in log
- Import 'log' function from math module (unused in this change)

This commit improves the diagnostic information provided by the
status retrieval process, making it easier to track when operations
started and completed, as well as the overall runtime of the script.

* feat(usb_handle): enhance status logging and timing information

- Add start and finish timestamps to status output

- Import 'log' function from math module (unused in this change)

This commit improves the diagnostic information provided by the
status retrieval process, making it easier to track when operations
started and completed, as well as the overall runtime of the script.

* refactor(usb_handle): improve logging and documentation

- Remove timestamp from initial result string in get_module_status()
- Add detailed docstring for creat_status_file() function
- Enhance start_process() function with improved documentation and logging
- Move start time logging from result string to logging.info() call

This commit improves code readability and maintainability by enhancing
documentation and refining the logging approach.

* refactor(usb_handle): simplify timestamp formatting in creat_status_file function

- Replace separate time.strftime() call with reuse of existing time_stamp variable
- Improve code readability and reduce redundancy in result string formatting
- Ensure consistent timestamp format throughout the status file creation process

* update linting issue

* refactor(usb_handle): improve timestamp handling and code organization

- Move timestamp generation to start_process function
- Add timestamp to result string before creating status file
- Remove unnecessary blank lines
- Update test case to reflect new timestamp handling

Add -i/--interactive flag to enable users to send custom AT commands in interactive mode.
This enhances the CLI flexibility by allowing direct AT command input during runtime.

Add new functionality to support interactive AT command sessions:
- Implement get_interactive_command() for user input validation
- Add handle_interactive_session() to manage interactive command flow
- Update start_process() to support both batch and interactive modes
- Add interactive flag parameter to control execution mode

This enhancement allows users to manually enter and execute AT commands
in an interactive session while maintaining the existing batch mode functionality.

Add comprehensive test suite for interactive AT command mode including:
- Test cases for get_interactive_command() with valid/invalid inputs
- Coverage for handle_interactive_session() with command sequences
- Tests for start_process() in both interactive and standard modes
- Validation of command processing and status file creation

This enhances test coverage for the interactive CLI features and ensures
proper handling of user input scenarios.

- Pass interactive flag to core function in cli.py
- Bump version from 0.1.4 to 0.1.5

- Add consistent trailing commas in function parameters
- Fix string quote style in test files (single -> double quotes)
- Improve readability of long function calls by breaking into multiple lines
- Format CLI argument definitions consistently
- Clean up whitespace in docstrings and function signatures

The changes focus on code style consistency across the codebase,
particularly in sierra_status/src and tests directories.
