Add read_into_dict function for simpler CSVY parsing

[Kaos599]

Closes #91

• Refactored read_into_dict Function:

  • Implemented a structured approach to read CSVY files, extracting both metadata and data sections.
  • Added error handling for cases where no metadata is found, returning an empty dictionary and printing a warning instead of raising an error.
  • Updated the function's docstring to clarify assumptions about the data structure, specifying that the first row contains column names.

• Updated Tests for read_into_dict:

  • Converted tests to dynamically handle files with or without metadata, outputting a UserWarning for files lacking metadata rather than raising assertions.
  • Implemented pytest.mark.parametrize to test multiple datasets seamlessly, enabling flexibility and scalability.
  • Updated metadata checks to verify general presence instead of specific keys, ensuring broader file compatibility.
  • Added logging to debug metadata contents and data types, aiding developers in tracing issues effectively.

• Improved Logging:

  • Integrated logging throughout the read_into_dict function and the test suite to track processing steps and outcomes, aiding in future debugging efforts.

• Code Formatting and Compliance:

  • Addressed code style issues, including import organization and compliance with PEP 8 guidelines.
  • Ensured that all functions and test cases have appropriate docstrings and are properly formatted.
