Customize testeff command for SST

[orelgueta]

The current implementation of the camera validation simulator which calls testeff would probably not work well with SSTs because a mirror list will not be set correctly. Konrad uses the following command for it (in Prod6):

bin/testeff -nm -alt 2147 -fatm atm_trans_2147_1_10_2_0_2147.dat -flen 2.152 -fcur 4.3 -spix 0.6 -fmir fake_astri_mirrorpos.dat -fref ref_astri-2d_2018-01-17_10deg.dat -fref2 ref_astri-2d_2018-01-17_25-40deg.dat -m2 -teltrans 0.921 -camtrans 1 -fflt transmission_sstcam_weighted_220512.dat -fang funnel_perfect.dat -fwl none -fqe PDE_lvr3_6mm_75um_uncoated_5.9V.dat 300 550 300 26 20

The important part which we do not use is -fmir fake_astri_mirrorpos.dat. This should be implemented.
