Lamport balance JS floating point issues

[marcospgp]

I'm having a discrepancy with lamport balances in test code and noticed this may be due to JS floating point inaccuracies.

I believe this may have been fixed in the @solana/web3.js package, but since the latest is v1.98.0 and Anchor currently depends on ^1.68.0 it may not yet be on a version containing that update.

Edit: actually there is a v2 it seems!

If I could be wrong here and there's something I could do to get a proper bigint or BN format when retrieving balance with:

(await provider.connection.getAccountInfo(
      publicKey
    ))!.lamports;

I'd appreciate the feedback!

If not, some info on when this update would be available would be great.

Thanks!
