Several important changes to improve efficiency of segmentation creation, including:
Avoiding unnecessary image resize operations in highdicom.seg.pyramid.create_segmentation_pyramid
Avoiding unnecessary construction of plane_positions when creating TILED_FULL segmentations
Avoiding unnecessary construction of source_plane_positions when creating segmentations under certain circumstances
Incrementally encoding frames of the pixel array when creating native encoded binary segmentations with bitpacking. This saves a lot of memory in some situations and saves a large allocation when the frames are concatenated at the end.
Using lower level pydicom functionality to avoid keyword dictionary lookups in key functions that are called in loops, in particular Segmentation._get_pffg_item and constructor of PlanePositionSequence
