[715] Enable handling of inverted latitude in reader.point

[georgespill]

reader.point raises a PointOutsideBounds error if the input coordinates are outside the dataset bounds. However, the current implementation assumes that bounds[1] < bounds[3]. This is not true for inverted latitude coordinates. This PR updates the implementation to handle the inverted case.

Fixes #715

See #696 for a similar issue

thanks @georgespill

do you thing we should had the same kind of warning as in https://github.com/cogeotiff/rio-tiler/pull/696/files#diff-aee02035a0c41599c6860bf04d8075994bb3f9e5b1d5d0595c0d02c5f4ddf596R50-R53 ?

would you be able to write a quick tests for this 🙏

[georgespill]

Yep, adding the warning is a good suggestion. Have added that along with updating tests

@vincentsarago would it be possible to publish a release with this fix included?

[vincentsarago]

@georgespill yes, I'm just waiting on #726 to get merged 🙏
