MemoryObject rewrite

I'm pretty happy with the current process and hooking code but the actual point of the library `MemoryObject`s are rather lacking, the current "magic" solution is very pretty and all but it's hard to type check and isn't completely perfect (see the state of Pointer i.e. DeferredPointer)

so instead I'd like to switch to a method based approach with simple .read and .write methods for properties
