Initial commit of the ClosedXML library

Establishes the foundational structure, core Excel functionality, and tooling. - Implements base components for cells, ranges, columns, and rows. - Integrates a custom calculation engine with a wide range of Excel functions. - Adds comprehensive support for styling, conditional formatting, data validation, comments, pictures, and charts. - Configures build setup, project metadata (NuGet), and developer guidelines. - Includes editor and Git attributes for consistent code style and line endings.
