sendTransaction not working.

[martinlasek]

Hey, I am getting an error back when trying to execute a transaction.
Someone from the crypto community said I'd need to also send along

skipPreflight=true since it's by default false as per Solana Documentation.

However this SDK does not provide the option to set the skipPreflight to true.

{
  "jsonrpc": "2.0",
    "error": {
      "code": -32002,
      "message": "Transaction simulation failed: Error processing Instruction 2: custom program error: 0xbc4",
      ...
    }
  }
}

This issue is solved by adding skipPreflight to the RequestConfiguration. Please merge PR-58.
