Ryan Malloy db54d05bed Makefile: use esptool directly, add LittleFS and erase targets ...

PlatformIO's built-in upload breaks on the S2 Mini (1200bps USB
touch reset disconnects the native USB port). All flash targets
now call esptool directly with the correct S2 partition offsets:
bootloader at 0x1000, firmware at 0x10000, LittleFS at 0x290000.

Also adds USB.begin() before Serial.begin() in main.cpp — required
for ESP32-S2 native USB-CDC to initialize properly.
