Scipion-em-aretomo

Users:
- Fix: re-align aligned tilt-series after having excluded views is now possible (validation is now a warning).

Users:
- Add input tilt-series excluded views management.
- Add odd/even tomograms reconstruction,
- Fix: amplitude contrast is read from the tilt-series metadata and passed to AreTomo.
- Do not support old AreTomo versions.
Developers:
- Write new tests with a better characterized test dataset.
- Tests renewed with a better adapted (real dark frames) test dataset and with cases of TS with excluded views.
- Add needsgpu attribute to the steps generation.
- Aln file writer method added to adapt the plugin to the API of AreTomo2-1.1.3 when only reconstructing the tomograms.

- Aretomo does nos fail when closing its output when process is killed
- Listed protocol's names are defaults ones.
- Tolerate failed tilt-series, avoiding the protocol interruption and generating a specific output for the failed
tilt-series.
- Force enable DW when saving extra IMOD output
Developers:
- Steps now use the tsId instead of the objId.
