Load(): Bug when interpolating data files with more than 4 dimensions

As reported in https://earth.bsc.es/gitlab/es/requests/issues/116 , cdo griddes cannot detect the grid in files with more than 4 dimensions. This makes Load() crash.

The CDORemap() can interpolate arrays with more than 4 dimensions by creating files with arrays of 4 dimensions maximum. The new Load should be programmed using the CDORemap to solve this issue.
