collapsing CityHashCrc256 to 20 bytes

[aj.bea...@gmail.com]

Hi,

I have a need to fold a 32 byte CityHashCrc256 down to 20 bytes.   Would there be a preferred way to do this to preserve the quality of the result?  Would simple truncation suffice, or possibly XORing some of the bits into a smaller set?

thanks!

Truncation should be fine.
