Enhance logging in FdsSqlOptions and related classes

- Updated FdsSqlOptions to accept an optional ILogger parameter for improved error logging.
- Modified FdsMfr and FdsMfrClient classes to pass the logger instance to FdsSqlOptions.
- Added detailed error logging in various methods to capture SQL execution issues and file handling errors.
- Improved documentation for FdsSqlOptions to clarify logging behavior.
- Updated Archive class to log compression errors, enhancing traceability of failures.
- Adjusted project configuration to suppress specific warnings related to transitive dependencies.
- Added NuGet.config to define package sources for dependency management.
- Updated submodule references for OCORE and related projects.
