Platform: Android on Samsung Tab S7 Plus
OS specifics: Android 13

Steps to reproduce

1. Load "Freehand Drawing" plugin
2. Plugin fails to load

Describe what you expected to happen

I get an error when loading io.github.personalizeerefrigerator.js-draw PluginRunner: "Plugin io.github.personalizeerefrigerator.js-draw: Unandled promse rejection: Error: Unable to require module os on mobil.. Promise: [object Promise]."
I tried another plugin (ABC Sheet Music) and it does work, but the Freehand Drawing one fails to load.

Thank you for letting me know!

The Freehand Drawing plugin uses temporary files (through fs-extra) to store and update drawings before sending them to Joplin. For now, there isn't a file system API available to mobile plugins.

Here are two possible ways of fixing this:

• Mock the fs-extra module using the mobile file system API internally
  • Being completely compatible with fs or fs-extra could be difficult
• Have Joplin provide its own file system API
