v0.9.3

• Set the TypeScript version as ^4.6.3 (#118)
• Fix a logic to get the base URL of a background image (#117)

v0.8.0

• New polygon drawing mode:
  • left-click will add point
  • right click will close polygon
  • double click will remove latest point
• the Bin button in the toolbar which deletes the canvas content will now empty the history and send back to Streamlit a blank state, even if update_streamlit is set to False.
• Right-click fires the send canvas data back to Streamlit event for all tools (not only the polygon) even if update_streamlit is set to False.
