Added helper script to copy the Community folders to local install

[ccrawford]

Description of changes

Added deploy_community.py in the root directory.

Automates deployment of MobiFlight Community Device's Community folder files to the local MF install directory for testing during development.

• Auto-discovers the custom device folder name by parsing *_platformio.ini files for custom_source_folder
• Copies all files from {project_folder}/Community/ to the user's MobiFlight Connector Community folder
• Uses Path.home() to automatically resolve the current user's directory
• Validates that both source and MobiFlight directories exist before copying
• Handles and alerts on errors/missing directories.
• Can be run by opening a shell windows and running 'python.exe deploy_community.py'

Fixes #21 by adding deploy_community.py script.

@ccrawford so MobiFlight must be installed under AppData/Local?
The files from device/Community folder gets copied, means all device.json, board.json and reset.hex/uf2 files. What is about the FW files?

[ccrawford]

I searched the documentation to see if MF gets installed in other places...it's been so long since I've done an install and that's where it is on my system. Is there a better way of determining where the install directory is? I guess it could be a parameter to the script, but that's starting to get less useful.

Few thoughts on the FW files:

1. This is for developers, not end users, and I assume you'll be uploading the firmware as part of the IDE build process.
2. The project I was working on when I made the script was for the ESP32, and MF doesn't support ESP32 firmware flashing.
3. I can add it if you think it would be valuable.
