feat: batch transfer

[chandrabosep]

Description: Implemented Batch Transfer Functionality

Added batchTransferCommand function to handle batch transfers.

• Validates input batch file and wallet existence.
• Verifies sufficient funds in the wallet before processing each transaction.
• Handles multiple batch transactions sequentially, ensuring that each transfer meets the wallet balance requirements.
• Provides user-friendly output messages with transaction status, including successful confirmations and failure cases.
• Improves error handling for common issues like invalid batch data, insufficient funds, or missing wallet.

Example Usage:

bun run batch --testnet --file ./batch.json

Batch File Format (batch.json):

[
  {
    "to": "0xA9ab8933Ff0467D51d13ea2bFECD81504Fc6f15a",
    "value": 0.000000001
  },
  {
    "to": "0xC0d2F97e6Bec1C04dA1188abA6F006AA4d04EEDC",
    "value": 0.000000002
  }
]

This file contains an array of transactions with recipient addresses (to) and the amounts to transfer (value) in tRBTC.

Hi!
I like what you are trying to do here but in order to be able to merge it, you are required to make some changes:

• The UX it is not flowing right...
  ** It is not nice for the user to fill in the same password over and over on each transaction. It should be asked once at the beginning.

  ** There should be a way of stopping the batch execution, instead of asking to confirm the execution of each transaction.

• The way to input the transactions also is not nice because the usage of this CLI doesn't allow the user to create files where it is being used. So my suggestion is that you can ask for the addresses and amounts through the command. Check this options:
  ** cli batch-send --interactive and then ask for the data like:
  Enter address: 0x1234...abcd
  Enter amount: 1.5
  Add another transaction? (y/n): y
  **. Use the json format to echo'd the addresses and amounts and then send it to the command
  echo '{"transactions":[{"address":"0x1234...abcd","amount":1.5},{"address":"0xabcd...1234","amount":2.0}]}' | cli batch-send
  ** Bonus points if you make it work with one of the options + the file you already did
