Ignore sampler warnigns caused by paramters outside the parameter limits

[kaiserls]

Description

EPI currently sets the log probability of a parameter point to -inf when the model is evaluated outside the parameter range limits. This leads to a large number of warning messages from the emcee mcmc sampler when a move leaves the parameter range. Warnings resulting from the subtraction of -inf in the red_blue move scheme are suppressed by this pull request. Other warning and error messages are not affected by this pull request.
