telink-usb-ota: reconstructing Telink USB-HID firmware updates

telink-usb-ota reconstructs Telink's USB-HID OTA update exchange as a Rust Linux host tool for querying and flashing a CIDOO V65 v2 keyboard. Its protocol notes specify 33-byte HID reports, START and FINISH opcodes, 16-byte data chunks, CRC-16/MODBUS and the next-chunk acknowledgement rule, derived from updater and firmware disassembly and checked by the author against hardware.
