natural gas with 99-01 years superposition

Natural gas has formed structure alike his own model 99-01 years.
So i added it with the slightly different time offset.
Also we gain big cycle end and the minimum(which in 1.8-2.1 range) by the march-may of 2023 (started in February 16).
Maybe i'll add in comments big picture with the cycles overview as i see it.
