Version 3

Hello! I've taken over maintenance for this package. It's been dormant for a few years and there are some big updates that I think are warranted, so time for a major release. Running list of things to be included, in no particular order:

- [x] Reduce scope by eliminating methods for Data Publishers - https://github.com/afeld/sodapy/pull/95. This will:
- Eliminate overlap with [socrata-py](https://github.com/socrata/socrata-py?tab=readme-ov-file#readme)
- Reduce maintenance overhead
- [ ] Raise `NotImplementedError`s for those removed methods
- [x] Switch primary class to be `Sodapy` (versus `Socrata`), to avoid overlap with socrata-py - https://github.com/afeld/sodapy/pull/105
- [x] Add error message if `Socrata` class from this package is used
- [x] Add type hints - https://github.com/afeld/sodapy/pull/93
- [ ] Ensure latest APIs are being used
- https://github.com/afeld/sodapy/pull/100
- https://github.com/afeld/sodapy/issues/109
- [x] Make the `app_token` optional - https://github.com/afeld/sodapy/pull/103
- [x] Split out an `all_datasets()` method - https://github.com/afeld/sodapy/pull/101
- [ ] Document it
- [ ] Have `limit`s on generator methods limit the overall number
- [ ] Update [examples](https://github.com/afeld/sodapy/tree/main/examples) - https://github.com/afeld/sodapy/pull/106
- [ ] Update the CHANGELOG
- [ ] Release

These changes are being done as pull requests to the `v3` branch: https://github.com/afeld/sodapy/compare/main...v3
