numbest yields additional trendlines; feature question/suggestion

[tsferro2]

great library, big thanks for sharing!

1 observation: when numbest is set to 1, I get 2 trendlines for both support and resistance, ie when set to 2 I get 3, and 3 yields ie 5 lines. Not sure if this is a bug or if I misunderstand the logic

Also wanted to ask (possible feature request):
is it possible to not display the average support and average resistance lines?
and
is it possible to set the sensitivity of the pivot identification so that ie it would only isolate more significant turning points?
