Wishes

1. Need more guidance and understanding of the codebase to properly implement.
2. Feedback on whether this is the right approach and guidance on the issues mentioned above. Just created the code based on my shallow understanding and assumptions. Don't even know the correct end result (not provided).

Issues

1. [RESOLVED] Wrong .env url ORD provided at the start resulting in axios error when creating dunes

2. Total Amount to be split and amount to be split is correct but when wallet is updated it is in correct.

For example here the split amounts are [33333334, 33333333, 33333333] but splits only have 100000 satoshis balance.

But when transferred and wallet is updated

4. When creating a new split with the new txid after initial dune split resulting in no dunes. Can't still figure out how to get the proper vout to source the utxo with dune. Assumed the last transaction in the utxo array is the utxo vout for the dune.
