Access the value of a FieldValue without throwing an exception

[hazeliscoding]

Issue

If we try to access a key that doesn't exist, we need to gracefully handle this if any error occurs or an exception is thrown.

How to Reproduce

var quickbaseClient = new QuickbaseClient("REALM_NAME", "USER_TOKEN");
var qbQuery = new QuickbaseQueryBuilder()
    .From("tableId")
    .Where($"{{'7'.CT.'{search}'}}")
    .Select([3, 7]) // We didnt select 150!!
    .Build();

var (response, errorResponse, isSuccess) = await quickbaseClient.QueryRecords(qbQuery);
if (!isSuccess)
{
    _logger.LogError($"Error querying Quickbase: {errorResponse?.Description} - {errorResponse?.Message}");
    return;
}

var dataFromQuery = response.Data.First();
worksheet.Cells["B5"].Value = qbResults["150"]?.Value; // This will throw an exception!!
