The spreadsheet-based RAM generation has been updated to support direct data extraction, as opposed the CSV approach. Pruned out obsolete code.

Code Review

This pull request refactors spreadsheet_ram.py by removing unused imports, the main driver, and several core methods including create_memory, read_physical_file, get_size_keys, and read_metrics_file. Additionally, it deletes several spreadsheet-related flow test files. The review feedback recommends further cleanup of now-obsolete components in SSRAMGenerator, such as self._process, self._pin_type_map, _import_custom_mappings, and their associated imports, to complete the pruning process.
