optimization of seeding (still not as good as needed)

set position for the two color mode (difference 3-4 ev)

timing of the direct beam with diode and laser
timing of the direct beam with YAG and laser
alignment of the lower branch of the SDL
timing pf the lower branch beam with YAG and laser

issues:
intensity and spectral purity of the seeded beam not really good
alignment of the mirrors have been tricky (previous values did not work)
