Missing export method in Ledger Tx

[manupadillaph]

Describe the feature you'd like

The method getCardanoTxReferenceInputs is not exported in the module Ledger.Tx (https://github.com/input-output-hk/plutus-apps/blob/main/plutus-ledger/src/Ledger/Tx.hs)

Others similar methos like getCardanoTxInputs are exported.

Describe alternatives you've considered

Add getCardanoTxReferenceInputs into the list of the module declaration
