Describe the bug
crc compute wrong when set ref_in to True

To Reproduce

import crcengine
import sys
import math

data = 0X20

input = data.to_bytes(math.ceil((hex(data).__len__() - 2) / 2), "big")

my_crc_algorithm = crcengine.create(poly=0x07,
								 width=8,
								 seed=0X55,
								 ref_in=1,
								 ref_out=0,
								 name="test",
								 xor_out=0x0)

result = my_crc_algorithm(input)
print(str(input.__len__()) + " " + hex(result))

output: 0x43
Expected output: 0xb0

website http://www.zorc.breitbandkatze.de/crc.html show a correct result:

Desktop (please complete the following information):

• OS: win10
• python 3.8.10

The least input data width is one byte by this time. So input 5 bits 10 bits data will get incorrect result.

Could add a input data len in param or binary mod to solve this problem? Thx.
