WebAssembly section framing
Wrap a raw payload with its section ID and unsigned LEB128 byte length.

How it works
Emit the section ID, the payload byte count as unsigned LEB128, and the unchanged payload.
Custom section ID 0 with one zero payload byte encodes as 00 01 00.
Limits
Section framing only. Supply a complete section payload, including any custom-section name. Ordering and payload semantics require a WebAssembly validator.
