* feat: Fixed the issue with nested unions relying on InitFromBuf. Problem: Issue #7569 Nested Unions were broken with the introduction of parsing buffers with an initial encoding offset. Fix: Revert the InitFromBuf method to the previous version and introduction of InitFromPackedBuf that allows users to read types from packed buffers applying the offset automatically. Test: Added in TestNestedUnionTables to test the encoding and decoding ability using a nested table with a union field. * fix: Uncommented generate code command
