Break apart generated C source and header files.

There's going to be a LOT of meta information around types at some point. It would probably be very wise to organize them into their own header files and have the top level header include all of them.

This can be done, but each header file will have to pull in headers for types upon which the type depends.

Changing my perspective on this a bit. I propose three different sub-header files:

• _types.h
• _packers.h
• _unpackers.h

I'd also suggest breaking the C files into two separate files:

• _packers.c
• _unpackers.c
