Refactor project_streamlines_to_map

[EmmaRenauld]

Quick description

• Rename scil_project_streamlines_to_map to scil_tractogram_project_streamlines_to_map. (With legacy + test)
• Since PR #810 , option --in_metrics in that script is not necessary anymore. Can now be done with combination of 1) scil_tractogram_project_map_to_streamllines. 2) scil_tractogram_project_streamlines_to_map.
• Note that with previous option '--in_metrics', there was a lot of preprocessing done to get values at each voxel crossed by the streamline (using uncompress), not only at the points of the streamline. This feature is not available anymore. Discussed with François. Can still be ~ achieved by resampling your streamlines first. Explanation has been added.
• Cleaned the main part of the script by adding new methods in io.streamlines and in dpp_and_dps_management.
• Had a circular import error. I had to move verify_compatibility_with_reference_sft from io.utils to io.streamlines.
• Fixing some parser.error and clarifying method names in Graham's work. ...
