Cerealed v0.2.0 - a(nother) D serialisation library

Ah, I see. No, it won't. Which answers the other question about 
serialising references to objects. I'm told this is a common 
problem, but this being my first bash at a serialisation 
library...

I was certain that Orange would be more mature and handle more 
corner cases than this library (or else it wouldn't be considered 
for inclusion in the std lib), but I wanted to share it since it 
works for what I'm doing, does things a bit differently and does 
what I need. Also, it was fun coding it.

If anything, if you think some of these ideas are worth it, feel 
free to use them. I'm just glad to not have to write the same old 
bit twiddling code for networking headers again!

True, I thought of doing something like it to simplify my MQTT 
broker implementation but ended up deciding against it.
