feat: feature editor with shape upload and drag&drop

[srijitcoder]

Context

Allowing users to upload/paste shape files directly to the drawtools

Implemented Changes

• Two attributes have been introduced for specific functionalities:
  • show-editor: Activates the editor within drawtools.
  • import-features: Enables the capability to upload, drag and drop files into drawtools.
• Users have the ability to upload, paste, or drag and drop three primary shapefile formats:
  • GeoJSON
  • TopoJSON
  • KML
• However, the primary shapefile format supported by the editor is GeoJSON. Any uploaded files in different formats will be automatically converted to GeoJSON.
• The editor includes a copy button to facilitate the copying of GeoJSON data.
• All OpenLayers (OL) implementations are encapsulated within eox-map, eliminating the need to import any OL files directly into eox-drawtools.
• The user interface for the editor is compatible with CSS variables.
• A beautified version of GeoJSON is generated whenever features are modified, utilizing a function implemented inside eox-map named parseFeature().

Note: I have only added a single test for copy rest not able to add because drawtool tests are partially implemented and not fully able to draw and update things.
