Support bigint

Describe the bug
When you try to get a table definition with a query like:

SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'database' AND TABLE_NAME = 'user'

App will crash with the error:

Exception: unsupported type <class 'jpype._jclass.java.math.BigInteger'>: 1

To Reproduce
In mysql/mariadb create a schema an try to get the table definition with a query like:

POST https://localhost:8080/Execute
User-Agent: aws-sdk-nodejs/2.647.0 linux/v12.16.1 promise
Content-Type: application/json
{
"secretArn": "arn:aws:secretsmanager:us-east-1:123456789012:secret:dummy",
"resourceArn": "arn:aws:rds:us-east-1:123456789012:cluster:dummy",
"sql": "SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'database' AND TABLE_NAME = 'user'",
"database": "database"
}

Docker will crash with this error:

Expected behavior
Like says in AWS Documentation (https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/data-api.html) it must return a LONG Data type.

@sdurban
Thank you for creating this issue and PR.

I didn't check the type. I'm happy :)

I have released a new version as 0.4.9
you can pull it from DockerHub.

Thank you very much.
