Added separate theory for iterated K-factors
This PR adds a line to the theory.db
file to include theory 217. This theory is equivalent to theory 200, except for the fact that the NNLO QCD K-factors for all the top quark pair data and for all of the Drell-Yan data have been recomputed with the central value of 210713-n3fit-001. The theory is available on the server and it seems to be correctly indexed. A report comparing two equivalent fits done with theory 200 or theory 217 will come soon.
