Update ROADMAP.md (#91)
This pull request updates the `ROADMAP.md` file to reflect the current status and future plans for the Python Driver for SQL Server. Key changes include clarifications about the public preview status, updates to feature availability across platforms, and the addition of new planned features like Bulk Copy (BCP) support. ### Updates to roadmap content: * Updated introduction to specify that the Python Driver for SQL Server is now in Public Preview. * Clarified that connection pooling is already available for Windows and will soon be extended to MacOS and Linux distributions. * Revised cross-platform support details to focus on Linux distributions, with MacOS support no longer explicitly mentioned. ### New feature announcements: * Added Bulk Copy (BCP) API support to the roadmap, highlighting its use for high-speed data ingestion and large-scale ETL workflows. ### Minor cleanup: * Removed unnecessary blank lines at the end of the file for better formatting. --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

Unlike existing Python SQL Server drivers, we are making substantial improvements to performance, maintainability, and usability by re-architecting the core internals. Our focus is on seamless integration between Python and C++, efficient memory management, better state handling, and advanced DBAPI enhancements.

We are undertaking significant structural changes to provide a clear abstraction between C++ code and Python. This will ensure better maintainability, improved performance, and a cleaner codebase. By leveraging existing pybind11 module, we aim to create a seamless integration between the two languages, allowing for efficient execution and easier debugging.
