Go Porth (Naive 1x1 Go translation from porth.py sim)

This translation is based on commit 5da80c1

The idea was not to write "idiomatic Go". I tried to translate 1x1 without any fancy modification to the original code. It was a relly cool experience.

The main project is hosted in Porth

My very fast computer specs:

CPU: Intel Celeron N3050 (2) @ 2.160GHz
GPU: Intel Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx
Memory: 1859MiB / 3852MiB

Native porth simulator

$ ./porth.py sim examples/rule110.porth
...
real    0m4,876s
user    0m4,769s
sys     0m0,048s

Go Porth simulator

$ go build -o porth main.go
$ ./porth sim examples/rule110.porth
...
real    0m0,026s
user    0m0,017s
sys     0m0,007s

I know that the comparation is very silly, but it is what it is, I also know that the language is meant to be self hosted, but again I enjoyed the exercise.
