[08] Finishes call/init implementation
...
Found 2 bugs:
0. ic+=10 is incorrect jump for the boolean compare methods
1. Another bug was in the write() method, which was increasing the instruction
counter even for label commands, which aren't supposed to do that.
Another minor issue in my interpretation of the "call" to `Sys.init`
which I was so far just doing via a jump. Changed that to a proper call
