crcmod doesn't package correctly, but on the upshot it implements in C: https://crcmod.sourceforge.net/
So someone packaged it, but there are provenance concerns to address - need diff and analysis to make sure it's trustworthy: https://github.com/ntamas/crcmod-plus
And then there is a more modern pure python version: https://github.com/Nicoretti/crc
I think I'd start by benchmarking crcmod's C impl against crc's pure python impl. It's likely overkill to care, but then again, people might be using this library on embedded systems.
