NES Tetris 19-4 B-Type DAS Clear + tiny life update

Done on Mesen Emulator with 1 frame of Run ahead.
19-4 is the highest humans have done with DAS, additionally there is a RNG manipulated 19-5 clear with preplanned inputs, very impressive.

I could have done a more detailled play by play though I don't think it's necessary because it's not really gonna help the people not familiar with the irks and quirks of nes tetris, and the people that are familiar will be able to tell where quicktaps happened, where das was regained on the next pieces, etc. Bunch of 7 taps were part of it, but not even an 8 tap was necessary. The O at the start really turned it into more of a 19-3.5.
