Pretty print oilist

[FerreolS]

oip list and oip list_baselines output are a bit messy and it is difficult to assess which value belong to which field.
As an example:

oilist 2018-12-14T051749_HD45677_IR-LM_IN_IN_cal_oifits_0.fits
target_name	s_ra	s_dec	t_exptime	t_min	t_max	em_res_power	em_min	em_max	facility_name	instrument_name	nb_vis	nb_vis2	nb_t3	nb_channels	
HD45677	97.072017	-13.05308	0.07500000298023224	58466.225046249856	58466.23150952865	47.39237355339858	2.841224613803206E-6	4.209076450933935E-6	VLTI	MATISSE	6	6	4	64

oip list and oip list_baselines should also print the same information order. As an example: facility | instrument | target name | target position .
