Psbtv2 operator role validation

[Shadouts]

This change adds several getter methods to PsbtV2 to support operator role validation:

• get isReadyForConstructor
• get isReadyForUpdater
  • get isReadyForSigner
• get isReadyForCombiner
• get isReadyForInputFinalizer
• get isReadyForTransactionExtractor

These getters return true when the psbt is ready for actions by the role it is named after. isReadyForInputFinalizer has yet to be implemented. It is likely that the psbt may be ready for more than one role in any state.

These getters are used in a few public methods to validate that the psbt is ready for the role for which is responsible of the action. The methods will throw if the psbt is not ready for that role.

• addInput, addOutput, deleteInput, deleteOutput, and dangerouslySetGlobalTxVersion1 checks isReadyForConstructor
• addPartialSig checks isReadyForSigner
