fix: native histogram: Simplify and fix addExemplar
mdIdx was redundant when len(exemplars)>1, so got rid of it, rIdx is enough. Don't compare timestamp of incoming exemplar to timestamp of minimal distance exemplar. Most of the time the incoming exemplar will be newer. And if not, the previous code just replaced an exemplar one index after the minimal distance exemplar. Which had an index out of range bug, plus is essentially random. Signed-off-by: György Krajcsovits <[email protected]>
