Issue:
Only one DynamoDB seeder possible per CDK stack
We encountered an issue in which multiple `DynamoDBSeeder` instances cause the stack deployment to fail. The problem seems to be missing permission to access the staged seed files on S3.

**I created a minimal stack to reproduce the issue: https://github.com/robdasilva/cdk-dynamo-db-seeder-s3-role-issue**

After looking into the synthesized stack output, it seems, that there is a policy attached to the `CustomServiceProvider` for each seed. However, they all reference the same resource—i.e. the seed file of the first seeder. The same behavior is seen for the `BatchWriteItem` policy of the respective DynamoDB tables: There is only **one** statement for the **first** table.

That causes the stack deployment to fail once it reaches any subsequent seeder, due to the `CustomResource` being unable to access the respective file on S3.
