Checks

• I agree to follow the MicroPython Code of Conduct to ensure a safe and respectful space for everyone.

• I've searched for existing issues regarding this feature, and didn't find any.

Description

Please consider adding a "watch" mode for mpremote, which will watch a root directory for changes and sync those changes to the micropython filesystem. This would make me much more efficient during heavy cycles of development.

Code Size

I think the efficiency gains for MicroPython developers would be great.

Implementation

• I intend to implement this feature and would submit a Pull Request if desirable.
• I hope the MicroPython maintainers or community will implement this feature.
