FR: add an option to store all scenes as .excalidraw.png files

Is your feature request related to a problem? Please describe.

The plugin now can generate png files with the scene embeded into them, but does not recognise them as editable excalidraw files.

Describe the solution you'd like

It'd be nice to be able to store drawings as .excalidraw.png files instead of separate .excalidraw and .png files. On a larger scale this is more convenient and it allows to easily share drawings within project teams as pointed out in #860.

The collaboration flow now is like this:

• Make a drawing locally
• Export the drawing as .png with embedded scene, publish to a shared git repo
• Whenever you need to change something, get that .png file and edit it within excalidraw.com or open in excalidraw.com, copy the contents back to obsidian
• Export the edited file as a .png with the scene embedded

The more convenient flow is something like this

• Make a drawing locally, store as .excalidraw.png
• Publish to a shared git repo
• Whenever you need to change something, get that file to your vault and edit it
• Publish the edited file to a shared git repo

Real-life usage scenarios

My current scenario is publishing excalidraw drawings as a part of a project's documentation. It's very desirable for these drawings to be editable by other members of our team who also use obsidian-excalidraw-plugin for their drawings.
