clean environment.yml

Installation with conda env create -f environment.yml failed on Mac:

Solving environment: failed
ResolvePackageNotFound:

• numpy==1.20.2=py38h09042cb_0
• qtlocation==5.12.9=ha925a31_0
• intel-openmp==2021.2.0=h57928b3_616
• libxslt==1.1.33=h65864e5_2
• (many more packages)

Currently the environment.yml is an exact copy of the used environment. It would be more user friendly

• if the environment.yml only lists the top dependencies, and let conda handle the dependencies of packages.
• only specific package versions are listed, when it is assessed that there is a problem with the latests

I see. For the moment I prefer the strict version list because this is a more correct record of how model setup was done. We have seen quite large differences in outcomes solely related to different GDAL versions so I am reluctant to let go of the exact version specification. May need a container solution to transfer environments to different machines.
