Wrong position of the "PRN / # OF OBS" header part in RINEX file
In some RINEX files, such as: ftp://igs.ensg.ign.fr/pub/igs/data/2016/044/HKSL00HKG_R_20160440000_01D_30S_MO.crx.gz and ftp://igs.ensg.ign.fr/pub/igs/data/2016/044/HKWS00HKG_R_20160440000_01D_30S_MO.crx.gz the header part with "PRN / # OF OBS" is placed at the end of the file. Hence reading these files leads to the following error: "org.orekit.errors.OrekitException: fin inattendue du fichier HKWS00HKG_R_20160440000_01D_30S_MO.crx".
