Check if the shift depends on h, ns and omega b about sbi_lens

Hi @dlanzieri so what's the verdict? :-)

[dlanzieri]

In the following table, I computed the fractional differences between the shift parameters, i.e I computed the shift at +/- 3sigma from the fiducial value divided by the shift at the fiducial.

The results from w0 are still a work in progress, they turned out to be a bit tricky!

Since our discussion and the fact we realized that the cosmological shift parameter varies with w0, Omega_m and sigma8, I'll close this issue!
