Add support for the generic Telechips firmware format checksums - use -tcc=sum if the header just contains a single checksum, or -tcc=crc if the header contains two 32-bit CRCs. Credit goes to Hein-Pieter van Braam for his work on identifying the (reverse) CRC32 algorithm used when calculating the two CRCs
