3-element Vec<(u32, u32)> = [elem0, elem1, elem2]
0x0c<elem0><elem1><elem2>
0c Compact length = 3
<elem0>... Each (u32, u32) encoded in sequence

const registry = new TypeRegistry();

// Encode a Vec<(u32, u32)>
const vec = registry.createType("Vec<(u32, u32)>", [1, 2, 3]);
console.log("Hex:", vec.toHex());
