Title: Adding support for crc-ccitt

CCITT is very similar to the existing crc16 functions, except that the
initial value is set to 0xFFFF. Test values were verified using pycrc,
and other test strings were verified from developer documentation for
the ReefNet Sensus device I'm working with (though not included in
test/crc.js).
