feat: Implement eth_getUncleByBlockHashAndIndex

[Boreas09]

Returns information about a uncle of a block given the block hash and the uncle index position.

Parameters :

• blockHash: [Required] A string representing the hash (32 bytes) of a block.
• uncle index position: [Required] A hexadecimal equivalent of the integer indicating the uncle's index position.

Returns :

A block object, or null when no block was found. The block object returned will consist of the following keys and their values:

• number: The block number. Null when the returned block is the pending block.
• hash: 32 bytes. Hash of the block. Null when its pending block.
• parentHash: 32 bytes. Hash of the parent block.
• nonce: 8 bytes. Hash of the generated proof-of-work. Null when the returned block is the pending block.
• sha3Uncles: 32 bytes. The SHA3 of the uncles data in the block.
• logsBloom: 256 bytes. The Bloom filter for the logs of the block. Null when the returned block is the pending block.
• transactionsRoot: 32 bytes. The root of the transaction trie of the block.
• stateRoot: 32 bytes. The root of the final state trie of the block.
• receiptsRoot: 32 bytes. The root of the receipts trie of the block.
• miner: 20 bytes. The address of the beneficiary to whom the mining rewards were given.
• difficulty: The hexadecimal of the difficulty for this block.
• totalDifficulty: The hexadecimal of the total difficulty of the chain until this block.
• extraData: The "extra data" field of this block.
• size: The hexadecimal of the size of this block in bytes.
• gasLimit: Maximum gas allowed in this block.
• gasUsed: Total used gas by all transactions in this block.
• timestamp: The unix timestamp for when the block was collated.
• uncles: (Array). An array of uncle hashes.
