Getting an error from flipper.js: bigint: Failed to load bindings, pure JS will be used (try npm run rebuild?)

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. What ledger are you using, e.g. Solana or Polkadot

solana-cli 1.14.23 (src:68c6fd13; feat:1879391783)

2. Here is the Solidity code I converted to Solana bytecode.

3. Provide both Solidity source and client code (e.g. TypeScript)

const { readFileSync } = require('fs');
const anchor = require('@coral-xyz/anchor');

const IDL = JSON.parse(readFileSync('./flipper.json', 'utf8'));
const PROGRAM_SO = readFileSync('./flipper.so');

(async function () {
    const provider = anchor.AnchorProvider.env();

    const dataAccount = anchor.web3.Keypair.generate();

    const programId = new anchor.web3.PublicKey(IDL.metadata.address);

    const wallet = provider.wallet.publicKey;

    const program = new anchor.Program(IDL, programId, provider);

    await program.methods.new(wallet, true)
        .accounts({ dataAccount: dataAccount.publicKey })
        .signers([dataAccount]).rpc();

    const val1 = await program.methods.get()
        .accounts({ dataAccount: dataAccount.publicKey })
        .view();

    console.log();

    await program.methods.flip()
        .accounts({ dataAccount: dataAccount.publicKey })
        .rpc();

    const val2 = await program.methods.get()
        .accounts({ dataAccount: dataAccount.publicKey })
        .view();

    console.log();
})();

5. Provide Solang version number (output of solang --version)

solang version v0.3.1

3. What behavior are you seeing?

$ node flipper.js

7. What behavior did you expect?

Expected behavior
I was hoping for the behavior that goes with the instructions provided in the readme.md file

Help?

You are right, there is a problem in this example. Line 18-20 should be:

    await program.methods.new(true)
        .accounts({ dataAccount: dataAccount.publicKey })
        .signers([dataAccount]).rpc();

However I recommend you follow the Getting Started with Solang Guide which is a much better experience.
