rework functions for interpolating projdata for scatter, mostly for B…
36e3b90 
…locksOnCylindrical

- Fixed inverse SSRB by always linearly interpolating between the two closest slices. This
  makes it work for BlocksOnCylindrical as well
- Rework extend_* functions: new extend_segment function that works on more cases, deprecated others
This works with BlocksOnCylindrical and view-offset. Fixes UCL#1177
- interpolate_projdata rewrite, including use linear interpolation in axial direction for BlocksOnCylindrical
- Deprecate interpolate_axial_position which used nearest neighbour
- Remove use_view_offset parameter from interpolate_projdata functions (always use view offset)
- Fixed UCL#1178 offset handling in sample_function_on_regular_grid, add sample_function_using_index_converter
- add test function
- Updated release notes.

Fixes UCL#1109
