Hi,

I am missing the CRC16 variant commonly used in the Automotive industry. See https://www.autosar.org/fileadmin/standards/R21-11/CP/AUTOSAR_SWS_CRCLibrary.pdf . It seems to be:

7.2.2.1 16-bit CCITT-FALSE CRC16

Which brings us to mrhooray/crc-rs#54 which was closed but IMHO not fully implemented. So the "CCITT standard" is probably equivalent to CRC_16_IBM_3740, fine. But the botched implementation (used in AUTOSAR) doesn't seem to be covered by any profile.

Is there a way to get it supported? That will probably require to add some flags (field) to the Algorithm parameter struct.
