0.4.0
 - BREAKING CHANGE: revert previous breaking change, because
   this way the reconstruction with ODTbrain/radontea remains
   straight-forward
 - enh: support str in `mode` when computing sinograms
0.3.0
 - feat: new options for sinogram generation
   - measurement duration (or specific times per angle)
   - specify simulated imaging modalities
   - simulate photobleaching and background fluorescence
 - BREAKING CHANGE: changed definition of angles in sinogram
   generation
0.2.1
 - ref: migrate to flimage
0.2.0
 - feat: add option to roll rotational axis (in-plane) during
   sinogram generation
 - feat: add capability to track progress of sinogram generation
 - feat: add possibility to add (random) displacements for each
   sinogram slice
 - fix: medium index not stored in exported sinogram file
0.1.0
 - add basic example to docs 
 - drawing refractive index and fluorescence phantoms
 - sinogram generation
 - basic functionalities (sphere element):
   - simple cell phantom
   - propagators: Rytov and projection
   - fluorescence projector
0.0.1
 - initial setup
