CRC python to Groovy

Hi,

I'm trying to support my Thermostat in Hubitat but for doing that I would need to convert this function from python to groovy:

def crc_count(bufer):
        hash = crc8.crc8()
        hash.update(bufer)
        return hash.hexdigest()

Lib is here crc8/crc8.py at master 路 niccokunzmann/crc8 路 GitHub

Anybody has an idea?
