++* number [prarm.poly]: short for the generated item in hexadecimal. For example, CRC-32 is 0x04C11DB7, ignoring the highest bit "1", i.e., the complete generation item is 0x104C11DB7.
++* number [prarm.init]: the initialization preset value of the register (crc) at the beginning of the algorithm in hexadecimal.
++* number [prarm.xorout]: the final CRC value obtained after heterodyning the calculation result with this parameter.
++* number [prarm.refin]: whether each byte of the data to be measured is inverted by bit, true or false.
++* number [prarm.refout]: after the calculation or before the heterodyning output, whether the whole data is inverted by bit, true or false.
