Python 2 methods to_bytes and from_bytes

[elelement]

Hi, your library was very useful to me. I was able to take pictures with my code but I was having a lot of unexpected errors and the docs didn't help me so much. Your code works great!

However, I think you're using python 3, because with Python 2 your code is incompatible. The solution is to change the following calls:

• int.from_bytes --->

def __from_bytes(self, bytes):
    return int(bytes.encode('hex'), 16)

• int.to_bytes -->

def __to_bytes(self, n, length, byteorder='big'):
    h = '%x' % n
    s = ('0'*(len(h) % 2) + h).zfill(length*2).decode('hex')
    return s if byteorder == 'big' else s[::-1]

Good job!

You already say in the description it is Python 3, sorry. Using this two functions makes it backward compatible.

Hey @elelement thanks for the feedback! Glad I was able to help. I had the same problem.

I'll get on trying out the changes. Unfortunately, my linksprite module recently died so i'm going to have to get a new one.
