Serialization no longer uses a fixed size buffer.

This is still WIP has I'm not sure we want the dependency on ctypes.foreign

In #65 I did something like this as well but it's been a while.

Thanks for the pointer.
Do you still have interest to push this through? If so, I'm happy to do some reviews

Do you still have interest to push this through?

Depends on whether there really is interest for it. This PR is a a subset of what I tried to do, so this might be easier to push through first. I also wanted to streaming parse from file without going through a fixed-size/dynamic buffer to minimize overhead, but I think there were some problems with doing it cleanly.

I'm not sure we want the dependency on ctypes.foreign

That's the concern I also had. There might be (at least ideally) a way around it: yallop/ocaml-ctypes#711.
