Add functions to interactive

[minhtien-trinh]

As discussed with @LucaMarconato @melonora and @josenimo, I added two small functions to annotate the shapes/visualize the sample id. The two functions are:

1. get_layer grabs the layer name and returns the layer if it matches the user input.
2. add_text_to_polygons adds annotations/sample names visually to the chosen polygons/shapes layer

When the user visualizes their data, annotations or simple sample id's could help in identifying samples and aid in analysis.
Example usage would be:

sample_id_list = gdf.index.tolist()
polygon_layer_name = 'Control'
interactive.add_text_to_polygons(polygon_layer_name, text_annotations)

1. Grab the sample id from the GeoDataFrame (index is used by default when linking a table with a shapes element)
2. Define the shapes layer (name of the spatial element shapes)
3. annotate (for now the default is: font size 10, red, center)

Ideally it will look like this:

Hi @minhtien-trinh thanks for your contribution! I reviewed the code and it looks great to me.

I ask you please two small adjustments before merging:

• the codecov job doesn't pass, could you please add some tests to cover the new code added?
• please update the changelog file. You can add the PR number #315 and your GitHub handle @minhtien-trinh, so this information will be parsed by the release notes.
• I adjusted most the of pre-commits (in another PR), but some of them, related to this PR, are still failing. Please fix them so the CI status passes.

Thanks!

@LucaMarconato I wrote tests, modified the changelog and changed my code so that pre-commit succeeds. For some reason docs fails now and I'm uncertain why. Can you help me?

It looks like bug in run on CI.
You may try to re-trigger CI pushing empty commit.

git commit -m "trigger ci" --allow-empty

@LucaMarconato Ready to merge :)

Two remarks for performance and readability.
