PYTHON BCP OPTIONS

For feature requests

FEAT: This pull request introduces a new data model for managing BCP (Bulk Copy Program) options in the mssql_python package. The changes add two @dataclass structures, ColumnFormat and BCPOptions, to encapsulate the configuration details for BCP operations in a structured and type-safe manner.

---

Summary

• mssql_python/bcp_options.py:
  • Added the ColumnFormat dataclass to define column-specific configurations such as prefix_len, data_len, and terminators (field_terminator and row_terminator).
  • Added the BCPOptions dataclass to represent BCP operation settings, including options for direction (in or out), file paths (data_file, error_file, etc.), batch size, error handling, and column configurations.

• [nitpick] The name server_col is ambiguous; consider renaming to server_column_index for clarity and consistency.

server_col: int = 1 # Option: (format_file) or (server_col)

Although this PR has just added the options for the BCP, I have added a few comments\best practices to be followed when you implement the logic. Make sure you adhere to all the validations I have suggested along with others wherever possible.
