16bit Forth

Been thinking again about finishing a frontend for a 16 bit Forth.
Last time I believe I got stuck at the Forth syntax macros

Need to be clear about what the idea is there.  Once there is a kernel
of 16 bit words, jumps and calls will no longer fit in single word
cells, so there is a clear tradeoff between speed and code size.

Other than that there are a lot of other things to figure out:
- stand-alone vs. hosted
- memory model

To simplify, my current opinion on this is:
- use staapl extended with 16 bit words for kernel work.
- build a stand-alone DTC on top of that
- use a dual serial interface: 2 serial ports, one for kernel, one for stand-alone
