Deadlock within SensorMapGeometryTransformer3D when running in multiprocessing for resampling algorithms 'near' and 'gauss'.

Deadlock under Linux for 'near' and 'gauss' if mp_alg=='bands'.

This line hangs forever: https://gitext.gfz-potsdam.de/EnMAP/sensormapgeo/-/blob/master/sensormapgeo/transformer_3d.py#L228

When further traced down, the actual resampling call within pyresample causes the deadlock: https://gitext.gfz-potsdam.de/EnMAP/sensormapgeo/-/blob/master/sensormapgeo/transformer_2d.py#L306

This seems to be caused by a GNU build of OpenMP used by pykdtree (dependency of pyresample).

Possible solution: Force to use the LLVM build of OpenMP under Linux.
