Simple serialization - an alternative to RLP that's much simpler.

The spec:

encode(string) = enc3b(len(string)) + string

Where enc3b(x) encodes x as three bytes, in big-endian format

encode(list) = enc3b(8388608 + sum(len([encode(x) for x in list]))) + \
               b''.join([encode(x) for x in list])

And that's it!

Examples:

cow -> \x00\x00\x03cow

[dog, horse] -> \x80\x00\x0e\x00\x00\x03dog\x00\x00\x05horse
