213 provide hd wallet implementation (#363)
* #213 rough sketch of needed functionality as a discussion basis * still work in progress * basic transaction working now. Still need to refactor a lot! But first good step. * #213 added WalletUtxoSupplier and removed getUtxo functionalities from Wallet.java Need to rework signing to get addresses. * #213 added stakekey registrations and address caching to wallet * #213 added Tests, WalletUtxoSupplier interface and DefaultWalletUtxoSupplier.java * #213 implemented signing with wallet. A UTXOSupplier will be passed. Thus removing the unneeded utxosupplier value in Wallet. * Refactor Tx sender wallet handling and clean up AbstractTx. Changed the sender wallet handling to return null instead of throwing an exception in Tx.java to allow flexibility in error management. Also, removed redundant 'amounts' field and its initialization from AbstractTx.java for a cleaner codebase. * Refactor TxBuilderContext and QuickTxBuilder Move the transaction building logic into a dedicated private method in `TxBuilderContext`. Refactor `QuickTxBuilder` to use the new build method and streamline the signing process, eliminating redundant code and improving code readability. * Refactor TxSigner to include TxBuilderContext * Normalize mnemonic phrase whitespaces * Update logging dependency to reload4j in build.gradle * Refactor: Change MnemonicUtil import path * Refactor Wallet signing and UTXO handling * Refactor Wallet class and update related tests Refactor Wallet methods and variables for better naming consistency. Remove unused methods and annotations. Add new test for scanning specific indexes in DefaultWalletUtxoSupplier. Update existing tests to align with the refactored method names and structures. * fix: changes to fix SonarQube errors --------- Co-authored-by: Satya <satran004@gmail.com>
