feat: Implement read from Athena functionality

[Christos-Hadjinikolis]

Context

It is required that Dynamicio can directly read dataframes from AWS Athena.

• Further details about getting started with dynamicio can be found here

Task

• Implement a WithAthena mixin class with a read_from_athena method that reads tables from AWS athena

Suggested Approach

Dynamicio already uses the boto3 library to access AWS. You'll want to continue using the boto3 class for authentication, and reading/writing where possible.

Please contact kit.burgess@miodo.io for instructions on how to test your code against a test AWS Athena instance.

Acceptance Criteria

• The read_from_athena method should read whole tables (every column & row) directly from AWS athena. select * from tablename.
• All existing tests pass.
• New tests written as required.
• Readme & docs are updated to reflect the new changes.

The Process

Please fork this repo, commit your changes on a branch, then send @miodohelper a PR request when your work is ready for review. Miodo will review the code before sending the PR for a final review by @Christos-Hadjinikolis.
