Bugfix
- catch neg ts vals StFroese (12)
Negative TS values occur when the iminuit optimization does not lead to the global minimum, but is close to it. If the proposed upper limit has a log-likelihood value smaller than the value from the optimization, the TS value is negative.
Fixed by setting `ts=0` if `ts<0` and close to zero `|ts|<1e-3` else an error is raised
