ngspice input files using optran

Pass Labs F5 turbo
thermal simulation
use optran for 4s and coarse steps to obtain stable temperature
then simulate transient with high resolution

HiPass3opamps_optran.cir
Just a check with three different OpAmps

TLV6001-test.cir, TLV9002-test.cir
These OpAmp currently allow op calculation only with optran
