Fixed issue where SensorMapGeometryTransformer raised an exception when trying to resample a 3D input array.
Fixed SensorMapGeometryTransformer.to_sensor_geometry() not working for resamp_alg='bilinear'.
The test_reproject module now tests all resampling algorithms instead of only one per test.

Updated version info.

Moved rasterio imports to function level to avoid static TLS conflict with pykdtree which is a dependency of pyresample.

Moved all pyresample imports to the top of the module to avoid Exception: dlopen: cannot load any more object with static TLS.

Moved all pyresample imports to methods to avoid Exception: dlopen: cannot load any more object with static TLS.

Fixed multiprocessing issue related to OpenMP multiprocessing within pykdtree as called by pyresample. Fixed type hints.

Fixed FutureWarning for numpy>1.16: arrays to stack must be passed as a "sequence" type such as list or tuple. Updated version info.

Revised SensorMapGeometryTransformer (now fully operable) and added corresponding tests. Added boxObj.buffer_mapXY() + test. Added type hints.
