Load table schemas from AWS Glue.
This loader fetches the schema of each table within a specified AWS Glue database. The schema details include column names and their data types, similar to pandas dtype representation.
AWS credentials are automatically loaded using boto3, following the standard AWS method: https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html
If a specific AWS profile is required, it can be specified and will be used to establish the session.
