Security vulnerabilities and automated fixes for usb security issues

A critical out-of-bounds memory access vulnerability was discovered in the FatFSUSB library used by the micro-journal ESP32 firmware, where memcpy operations on a sector buffer accepted attacker-controlled offset and size values from USB SCSI commands without any bounds validation. A malicious USB host could craft SCSI READ/WRITE commands to corrupt memory, potentially crashing the device or executing arbitrary code. The fix adds a simple but essential bounds check before every memcpy operation,
