Render extracted shorelines as points instead of interpolated linestrings

Description:
Instead of utilizing Coastsat's function to interpolate the points for the extracted shorelines, the proposal is to save them directly as points within a GeoJSON file. Subsequently, these points should be rendered on the map.

Proposed Solution:

1. Modify the extraction function to save shoreline points directly without interpolation.
2. Save these points to a GeoJSON file.
3. Update the map rendering function to display these points.

Alternative Solutions:

• Consider providing an option for users to toggle between viewing interpolated linestrings and raw points, catering to different user preferences.

Benefits:

1. Direct representation of extracted data without interpolation, ensuring accuracy.
2. Potentially faster processing and rendering times as interpolation is skipped.
3. Provides a clearer view of data density and distribution.

Drawbacks:

1. Without interpolation, the visual representation might appear fragmented or less continuous.
2. Some users might prefer the visual continuity provided by linestrings.

Additional Context:

• This change might affect other visualization tools or functions that rely on the current interpolated linestrings format.

pip install coastseg==0.0.75.dev1
This feature has been implemented in version 0.0.75.dev1. The shorelines are rendered on the map as individual points. Any shorelines that were created before will be converted the MultiPoint so that they can be rendered as points on the map. A new behavior coastseg has is it now saved two extracted shoreline files

1. extracted_shoreline_points.geojson

• Contains the shorelines as MultiPoints

2. extracted_shoreline_lines.geojson

• Contains the shorelines as LineStrings
