70d9f116fd
Adds an experiment that codes an end-of-orientation symbol for every eligible zero encountered in scan order. This cleans out various other sub-experiments that were part of the origiinal patch, which will be later included if found useful. Results are slightly positive on all sets (0.1 - 0.2% range).
