ARINC 615 Download Operation: Compare Check Value of Files against expected one.

The Target Data Loader can transmit the expected checksum as TFTP option to the Host Loader. When so, the Host loader shall calculate the check value itself and compare against the expected from. If the check fails, this should be noted within the download information. The transfer shall complete (No abort).

Note: Do not implement the check within the "File Completion" Handler, as this handler runs in the context of the network I/O Task which blocks during calculation the transfer of TFTP packets.
