Irrigation module allowing three irrigation methods for one cft in one pixel and transient irrigation techniques share data under future scenarios

[YiYaoVUB]

Followed by my last issue #1696 , I want to further extend the irrigation module. In my last development, we chose one irrigation method (drip, sprinkler or flood) for one CFT in one pixel, which is still a bit limited, especially when we want to include transient irrigation techniques share in the simulations. In this development, my current plan is:

1. Extend the CFTs from 64 to 128, which means, for every crop, we have one rainfed and three irrigated columns (different method). With this we need to expand the pftconMod.F90 and some modules using the variables in the pftconMod.F90.
2. Create the dataset of future irrigation techniques share under future scenarios and implement it in CESM landuse timeseries data.
   This idea is still at an initial stage and will update every time we need to do a modification.

Thanks for posting this intention, @YiYaoVUB . This seems to have pretty intensive changes to memory, parameter files and input data (land use time series). If you can make it work for your own research I think it's great, but my initial reaction is that incorporating this back into CTSM would require more careful discussion and consideration.

Thanks, Will!

This won't make the CLM6 timeline, so removing this from the highlights board. Sorry @YiYaoVUB
