Merge

Creates an unsigned transaction for merging two Solana stake accounts.

Supports both standard recent blockhash nonces (default) and durable nonces (more information here):

For standard recent blockhash nonces, leave nonce_account and nonce_authority empty.
For durable nonces, define a nonce_account.
