Breaking Changes

Removed TxBuilderConstants from the public API. Use cardano-cli, cardano-db-sync, or third-party APIs to retrieve the latest cost models and protocol parameters.
The to_bech32() method for DRep now requires a boolean flag to specify the new CIP-129 format. Additionally, the function's output has been updated to align with the latest CIP-0005 specifications.

Updates

The from_bech32() method for DRep now supports CIP-129 and both versions of CIP-0005.
The TxInputsBuilder now includes a new set of functions: add_regular_utxo, add_plutus_script_utxo, and add_native_script_utxo. We recommend using these functions instead of the add_***_input methods, as the new ones handle referenced input fees automatically.
A new do_not_burn_extra_change flag has been added to the TransactionBuilderConfigBuilder. This flag prevents burning extra ADA when it is not possible to create a new change output. By default, this flag is unset, and you need to enable it manually if needed.
Fixed the equality function for MultiAsset when the assets list is empty.
