feat: loosen ffi import utxo requirements (#4126)
Browse files Browse the repository at this point in the history
Description
---
- Made import UTXO less strict for the FFI - _source public key_, _features_ and _covenant_ are now optional inputs.
- Added missing `TariTransactionSendStatus` decode and destroy methods to the FFI interface file `wallet.h`.

Motivation and Context
---
- The facet is missing some non-critical parameters
- Methods to de-structure `callback_transaction_send_result` were missing in the FFI interface file `wallet.h`.

How Has This Been Tested?
