i just pushed changes to my branch that allow a layer argument for the hover observer!

This is pretty much all it takes in the JS:

const options = x.hover_events.layer_id ? { layers: [x.hover_events.layer_id] } : undefined;
const features = map.queryRenderedFeatures(e.point, options);

and adding the option for the layer_id argument in the enable_shiny_hover R fcn. I can open a PR later if we want

@kmcd39 awesome! feel free to open a PR but I can probably just plug that in if that's all we need to do. appreciate that! another user just requested it, so perfect timing.

@kmcd39 this is now implemented! I used your code but just adapted slightly to allow users to pass a vector of layer IDs if they want to target multiple layers on hover. Thank you for contributing!

okay amazing!!
I was on other projects for a while (and tbh am quite new to just github for actual collaborations) but just did a pull request to include the get_viewpoint_features as well, if you think that's worth including.
