[0.7.0] - 2021-05-14

initial_drawing is now used as the initial canvas state. If None provided then we create one on the Python side. This provokes the following changes:
- a change in background_color will reset the drawing.
- background_color will override the background color present in initial_drawing.
- if background_image is present then background_color is removed from st_canvas call.
Upgrade Fabric.js to version 4.4.0.
Toolbar is now on the bottom left to account for large canvas width.
Add argument to make the toolbar invisible.
Make stroke_width the minimum size constraint to create a rectangle and circle. Thanks hiankun for the PR!
