Fixed
- Ensure `py.typed` files end up in binary wheel distribution, which may break type checking for consumers

Added
- Run tests against Python 3.11
- Stop ignoring imports during type checking

Added
- Add `py.typed` file so mypy can check against package types in downstream applications

Changed
- Use interpolation for logging messages to avoid wasted computation

Changed
- Move from Travis CI to GitHub Actions for testing and publishing
- Use PEP 517 builds

Added
- Testing matrix and trove classifiers for Python 3.9
- Type hints for all classes, methods, and functions

Removed
- Support for Python 3.6 has been removed due to its impending end of life and the desire to leverage features from 3.7

Changed
- Remove Python 3.10 testing and support for now, as Travis CI only has Python 3.10.0a5 which isn't compatible with recent pytest-randomly releases
- Indicate (by renaming) that all functions in the `client` module are private, except for `call`

Added
- Ability to specify `proxies` for a `Service` definition so all calls to the service use the defined proxies
- Ability to specify `auth` for a `Service` definition so all calls to the service use the defined authentication
- Ability to specify `return_raw_response_object` at the endpoint level, overridden by any value specified at call time

Maintenance
- Add [pre-commit](https://pre-commit.com/) configuration for earlier linting and formatting checks
