Improve ascii table, add --ofs flag, enhance documentation (#67 )

* enhanced documentation * added --ofs parameter use 2 spaces for ascii output but it is customizable with --ofs, which is also being used by CSV mode (whose defaults remains unchanged) * improve ascii table output, use 2 spaces as OFS by default
Fix excess spaces on normal ascii table output (#66 )
