another round of (hopeful) improvements
...
add indirect bit to "sys" definition
set initial ".." (output base) to 4096 (not yet honored)
add "ptr" output format (binary in paper tape reader format: 3 frames of 6 bits)
remove IOT instrictions (system source uses sop.s)
always write labels to "n.out"
add debug output
fix multiply defined error handling (process symbolic labels on both passes)
