Add stake and unstake commands to Shardeum CLI

[chrypnotoad]

Add shm:stake and shm:unstake commands to the Shardeum CLI.

• shm:stake command

  • Takes amount of SHM and node's public key as inputs.
  • Sends internal transaction to contract address 0x0000000000000000000000000000000000010000 with internalTXType: 6.
  • Sends tokens with the transaction (value = stake amount).
  • Uses gasLimit of 30000000.
  • Encodes transaction data as hex-encoded JSON string.

• shm:unstake command

  • Takes node's public key as input.
  • Optional force flag for forced unstaking.
  • Sends internal transaction to contract address 0x0000000000000000000000000000000000010000 with internalTXType: 7.
  • No value sent with the transaction.
  • Uses gasLimit of 30000000.
  • Encodes transaction data as hex-encoded JSON string.

• README.md

  • Adds usage examples for shm:stake and shm:unstake commands.
