Paginate-json

- New `--key rows` option for specifying the key in a root-level object that should be iterated over. [7](https://github.com/simonw/paginate-json/issues/7)
- The `--jq` option now works with either [jq](https://pypi.org/project/jq/) or [pyjq](https://pypi.org/project/pyjq/) installed as an optional dependency. [#10](https://github.com/simonw/paginate-json/issues/10)
- No longer produces debug logging to `stderr` by default - you can now enable that with the new `-v/--verbose` option. [8](https://github.com/simonw/paginate-json/issues/8)
- If a response returns an object instead of a list, `paginate-json` now treats that as if it were a list of a single object. [9](https://github.com/simonw/paginate-json/issues/9)
- Now fails with an error if it gets an HTTP response with a non-200 status code, unless you pass the `--ignore-http-errors` option. [13](https://github.com/simonw/paginate-json/issues/13)

- Now handles relative URLs in `link` HTTP headers. Thanks, [Geoff Baskwill](https://github.com/glb). [#5](https://github.com/simonw/paginate-json/issues/5)
- [README](https://github.com/simonw/paginate-json/blob/master/README.md) now links to example tutorials.
