Irdap

Corrected error due to numpy.int deprecated and warning on IP model

Corrected an error due to a scikit-image function being deprecated
Changed to new ESO e-mail address

Updated code so that it correctly handles the change of the header names INS4 DROT2 BEGIN and INS4 DROT3 BEGIN to INS4 DROT2 START and INS4 DROT3 START in the FITS files

Corrected a bug that prevented reductions to be performed when dark and flat files are included in the raw subdirectory

Added command-line option (irdap --print) to toggle printing of log statements in the terminal

- Implemented two new configuration parameters (combination_method_polarization and combination_method_intensity) for the computation of the final Q-, U-, I_Q- and I_U-images. The Q- and U-images can now be computed using least squares (as was previously the only option), the median and the trimmed mean. The I_Q- and I_U-images can be computed from the mean (as was previously the only option), the median and the trimmed mean
- Old configuration files that do not have these parameters can still be used: IRDAP automatically uses the default least squares and mean options if these new configuration parameters are missing from the configuration file
- Some minor additional improvements
