Allow "limit" taxmode in streams to use data before or after the years running over if available

I've found that the "limit" option for taxmode can be a really good way to find simulation setups that are invalid and will produce bad results. Sometimes the "extend" option is used where it shouldn't as the first or last value in a daily (or even yearly) varying series is a horrible thing to do. As well as the "cycle" option will go back to the beginning year of a transient period when it reaches the end, which is another horrible thing to do.

The problem with limit as it's currently implemented (both in MCT and NUOPC) is that it only considers data within the years that you are running over. So it won't use data outside that range even if it's available in the time-series. In many cases with our datasets we added "extra" data before or after to eliminate this kind of problem, but that data is essentially unavailable because the algorithm doesn't allow it to be used. I think it should only use the one time-sample before and the one time-sample after the years you are running for, but if that data is there it should use it.

I found this problem in a CTSM issue:
