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 interp
