Feature/improved api client

[dylanburkey]

Overview

This PR introduces a new GameAPIClient class that improves error handling and implements smart retry logic for the GAME SDK. The changes make the SDK more resilient to transient failures while providing clearer error messages to users.

Key Changes

• Created new GameAPIClient class with comprehensive error handling
• Implemented intelligent retry logic with exponential backoff:
  • No retries for authentication (401) and validation (422) errors
  • Automatic retries for transient failures (network errors, 500-series errors)
• Added full test coverage for all error scenarios
• Updated .gitignore to exclude coverage reports

Testing

• Added comprehensive test suite with 100% code coverage
• Tests verify correct handling of:
  • Authentication errors
  • Validation errors
  • Server errors (500, 502, 503, 504)
  • Network connectivity issues
  • Request parameters and endpoint handling

Impact

These changes will improve the SDK's reliability by:

• Automatically recovering from transient failures
• Providing clearer error messages to users
• Reducing unnecessary retries for non-recoverable errors

I'm not sure if we need this, given that we have a pyproject.toml
