getTokenAccountsByOwner

[wiyarmir]

TL;DR

Added support for retrieving SPL Token accounts by owner with optional mint or program ID filtering.

What changed?

• Created a new PublicKeyBase58Serializer for handling Base58 serialization of public keys
• Implemented getTokenAccountsByOwner methods with support for filtering by mint or program ID
• Added data classes to represent token account information including account details, token amounts, and ownership data

How to test?

// Test retrieving token accounts by owner and mint
val tokenAccounts = client.getTokenAccountsByOwnerAndMint(
    account = ownerPublicKey,
    mint = mintPublicKey
)

// Test retrieving token accounts by owner and program ID
val programTokenAccounts = client.getTokenAccountsByOwnerAndProgramId(
    account = ownerPublicKey,
    programId = programPublicKey
)

Why make this change?

This addition enables querying and filtering SPL Token accounts, which is essential for applications that need to track token holdings, manage token accounts, or analyze token-related activities for specific accounts on the Solana blockchain.
