Alpha variation but same thcovmat

[andreab1997]

We want to add the possibility of doing thcovmat fits with theories computed with alpha=0.117 and alpha=0.119 (using however the usual thcovmat computed with alpha=0.118). This PR will contain:

• The new list of theoryids for the construction of the thcovmat
• The updated datasets containing the four new theories (528=NLO,alpha=0.117, 529=NLO,alpha=0.119, 530=NNLO,alpha=0.117, 531=NNLO,alpha=0.119)
• Putting the new theories in the server

Why not extend pointprescriptions.yaml by adding the alphas mappings? Would make it a bit more readable.

Maybe I did not understand but in this case I just want to have exactly the same thcovmat just used together another theoryid. So the point prescription is really the same and the fact that I am changing alpha has 0 effect on the thcovmat.

Oh nvm, I thought you wanted to vary alphas itself as opposed to R/F scales at different central alphas.

Nono, this is just what I have been asked to do: a fit done with varied reference values of alpha (0.117 and 0.119) but with the exact same thcovmat that we use with alpha=0.118.

PS: Since you are already here, let me give you the pleasure of reviewing this ;)

I'm not going to check if the theory content is all correct...
