:: Usage:
::   upload.bat                     Auto-detect port, compile + upload
::   upload.bat -p COM3             Specify port
::   upload.bat --monitor           Open serial monitor after upload
::   upload.bat --clean             Clean build cache first
::   upload.bat --verbose           Full compiler + avrdude output
