Improve multistart documentation, bugfix
- Split out llhist and parhist documentation - Add example code for multistart - Create a multistart vignette, because the example code fails when run by pkgdown - Fix multistart for the case of mkin transformations in the saem fit

+In case the online version of this help page contains error messages
