84 - HTTP Error code handling 400+ (#87)

* feat: Enhance HTTP client error handling with custom exceptions

- Implement hierarchical exception system with base NHLApiException
- Add specific exceptions for common HTTP status codes (404, 429, 400, 401, 5xx)
- Create centralized error handling in _handle_response method
- Add comprehensive test suite with pytest for all error scenarios
- Improve error message formatting to include both request context and API response
- Handle edge cases for malformed JSON and non-JSON responses
- Add type checking for response parsing

Tests cover:
- All HTTP error status codes
- Success responses
- Non-JSON responses
- Malformed JSON handling
- Query parameter handling
- Verbose logging behavior

Breaking changes: None - extends existing error handling functionality
Closes #81

* README bugfix

* Fix: stats.team_summary() double encoding issue in notebooks
