REGIS dataset has changed

Suddenly, hydraulica conductivities of -9999 are popping up in the REGIS retreived data. The nlmod tests are failing and so do all models using REGIS.

You are right... There seems to be a new update of REGIS:

The new dataset contains -9999 instead of NaN-values. I think we should make a new update this week. I will see if I can quickly fix it.

I have just updated the main branch and released version 0.8.1, where this issue should be fixed.
