Calculate and verify a hash of a block from blockheader

For example, let's consider Block#125,552

./rpc_verify_hash.py 00000000000000001e8d6829a8a21adc5d38d0a473b144b6765798e61f98bd1d

All components concatanated into single hex string:
b'0100000081cd02ab7e569e8bcd9317e2fe99f2de44d49ab2b8851ba4a308000000000000e320b6c2fffc8d750423db8b1eb942ae710e951ed797f7affc8892b0f1fc122bc7f5d74df2b9441a42a14695'

Final hash: 00000000000000001e8d6829a8a21adc5d38d0a473b144b6765798e61f98bd1d is calculated correctly
