Many encryption algorithms require the message to be encoded as an integer. Python provides the method from bytes of the class int that converts the bytes (bit-string) representing the string into an integer. To convert a string to bytes the str.encode()) can be used.

The byteorder parameter can be either
?’big’ for big-endian: an order where the big-end or the most significant byte in string sequence is at the beginning of the byte array
?’little’ for little-endian: an order where The little-end or the least significant byte in string sequence is at the end of the byte array

Write an equivalent function to Python int.from bytes() library function
