    Class Session

    Manages the unrolling process of a virtual output back to the Bitcoin blockchain.

    The Session class implements an async iterator that processes the unrolling steps:

    1. WAIT: Waits for a transaction to be confirmed onchain (if it's in mempool)
    2. UNROLL: Broadcasts the next transaction in the chain to the blockchain
    3. DONE: Indicates the unrolling process is complete

    The unrolling process works by traversing the transaction chain from the root (most recent) to the leaf (oldest), broadcasting each transaction that isn't already onchain.

    const session = await Unroll.Session.create(vtxoOutpoint, bumper, explorer, indexer);

    // iterate over the steps
    for await (const doneStep of session) {
      switch (doneStep.type) {
        case Unroll.StepType.WAIT:
          console.log(`Transaction ${doneStep.txid} confirmed`);
          break;
        case Unroll.StepType.UNROLL:
          console.log(`Broadcasting transaction ${doneStep.tx.id}`);
          break;
        case Unroll.StepType.DONE:
          console.log(`Unrolling complete for virtual output ${doneStep.vtxoTxid}`);
          break;
      }
    }
