Irdap

- Put temporal uncertainty as uncertainty of the star polarization in the log file, added the accuracy of the Mueller matrix model and clarified which uncertainty to quote in papers.
- Made IRDAP check for updates when run
- Implemented correct link to ADS of van Holstein et al. (2020) in program and documentation

- Clarified meaning of standard deviation of fitted center coordinates in log file
- Very minor correction to computation of HWP angle from headers
- Corrected minor bug when computing polarimetric efficiency when the number of Q and U cycles is unequal
- Added warning when spread of star polarization per HWP cycle is large and suggest to try normalized double difference

- Added polarimetric efficiency to crosstalk/transmission plot, a print statement with the range of the polarimetric efficiency of the observations, and a warning in case of low polarimetric efficiency
- Corrected a bug in the checks of flux_annulus_star
- Corrected a bug that when mean combining ADI+PCA-images only the first frame of the cube was written to the FITS-files

- Corrected bug introduced in v1.2.0 with computation of DoLP and AoLP of star when there is an unequal number of Q and U measurements

- Added computation of statistical uncertainty (photon and background noise) on measured star polarization in PDI part
- Added contrast curves for the detection of polarized extended sources and polarized point source with PDI

- Added angular differential imaging (ADI) including principal component analysis (PCA) of total intensity images for pupil-tracking observations
- Added mean combination of ADI final images to command-line option
