12/// We introduce a builder-pattern format for creating transaction outputs
13/// This is because:
14/// 1. Some fields (i.e. data hash) are optional, and we can't easily expose Option<> in WASM
15/// 2. Some fields like amounts have many ways it could be set (some depending on other field values being known)
16/// 3. Easier to adapt as the output format gets more complicated in future Cardano releases
