/**
 * The PsbtV2 class is intended to represent an easily modifiable and
 * serializable psbt of version 2 conforming to BIP0174. Getters exist for all
 * BIP-defined keytypes. Very few setters and modifier methods exist. As they
 * are added, they should enforce implied and documented rules and limitations.
