Combine prepareCompute and Retries

[Woody4618]

• Added a new helper to make sending transactions only one line: sendTransactionWithRetryAndPriorityFees

Examples usage:

    const initTransaction = await program.methods.initialize().transaction();

    await sendTransaction(
      connection,
      initTransaction,
      [keyPair],
      10000 // priority fee
    );

Why no longer exporting this?

I think it will be confusing people and they will think the sendTransactionWithRetry is better than sendTransaction. SendTransaction uses sendwithRetry internally

Thanks :)
The BN change also seems to fix the anchor issue!
