Add PartialDataColumnSidecar, PartialDataColumnPartsMetadata, and PartialDataColumnHeader types from consensus-specs #4558. These types support cell-level dissemination via Gossipsub partial messages, allowing individual cells to be sent instead of full data columns for more efficient data availability sampling. 🤖 Generated with AI assistance
Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request introduces new SSZ data structures required for the Fulu upgrade's cell dissemination mechanism. These types facilitate more efficient peer-to-peer data transmission by allowing for partial column communication rather than full data columns, aligning the codebase with the latest consensus specifications.

This line exceeds the 100-column limit specified in the repository style guide (line 400). Please reformat it to adhere to the style guide. zig fmt should handle this automatically if you break the line inside the function call's arguments.
